Is 3 8 Greater Than 1 3? Quick Answer

If we want to compare two fractions, we must have the same denominator. So we need the LCM (least common multiple) of #4# and #3#, which is #12#. So we need to multiply 4 by #3# and 3 by #4#

Remember that whatever you do below must be done above.

For #3/4# we multiply 3 down (denominator), so we need to multiply #3# up (numerator).

For #2/3# we multiply #4# down, so we need to multiply #4# up.

#(3xx3)/(4xx3)=9/12# and #(2xx4)/(3xx4)=8/12#

Now just look at the counts of the two answers. #9# is bigger than #8#, so #9/12# is bigger! #9/12# was originally #3/4# .

So #3/4# is greater than #2/3# .

I hope you understood this and my source is my knowledge!

Lesson 2: Compare and reduce fractions

compare fractions

In Introduction to Fractions, we learned that fractions are a way of representing a part of something. Fractions are useful because they tell us exactly how much we have of something. Some fractions are larger than others. For example, which is larger: 6/8ths of a pizza or 7/8ths of a pizza?

In this image we can see that 7/8 is larger. The figure makes it easy to compare these fractions. But how could we have done that without the pictures?

Click through the slideshow to learn how to compare fractions.

We have already seen that fractions have two parts.

One part is the top number or numerator.

The other is the bottom number or denominator.

The denominator tells us how many parts a whole has.

The counter tells us how many of these parts we have.

When fractions have the same denominator, it means they split into the same number of parts.

This means we can compare these fractions just by looking at the numerator.

Here 5 is more than 4…

Here 5 is more than 4… so we can say that 5/6 is more than 4/6.

Let’s look at another example. Which of these is bigger: 2/8 or 6/8?

If you thought 6/8 was bigger, you were right!

Both fractions have the same denominator.

So we compared the counters. 6 is greater than 2, so 6/8 is more than 2/8.

As you’ve seen, when two or more fractions have the same denominator, you can compare them by looking at their numerators. As you can see below, 3/4 is larger than 1/4. The larger the numerator, the larger the fraction.

Comparing fractions with different denominators

On the previous page we compared fractions that have the same lower numbers or denominators. But you know that fractions can have any number as a denominator. What if you need to compare fractions with different lower numbers?

For example, which of these is larger: 2/3 or 1/5? It’s hard to tell just by looking at her. After all, 2 is greater than 1, but the denominators are not equal.

If you look at the picture, the difference becomes clear: 2/3 is larger than 1/5. With an illustration it was easy to compare these fractions, but how could we have done that without the picture?

Click through the slideshow to learn how to compare fractions with different denominators.

Let’s compare these fractions: 5/8 and 4/6.

Before we compare them, we need to change both fractions so that they have the same denominator, or bottom number.

First we find the smallest number that can be divided by both denominators. This is what we call the lowest common denominator.

Our first step is to find numbers that are divisible by 8.

Using a multiplication table makes this easy. All numbers in the 8-series can be divided by 8 without a remainder.

Now let’s look at our second denominator: 6.

We can use the multiplication table again. All numbers in the 6-series can be divided by 6 without a remainder.

Let’s compare the two lines. It looks like there are some numbers that are divisible by both 6 and 8.

24 is the smallest number that occurs in both series, so the lowest common denominator.

Now let’s change our fractions so that they both have the same denominator: 24.

To do this, we need to change the numerators in the same way we changed the denominators.

Let’s look at 5/8 again. To change the denominator to 24…

Let’s look at 5/8 again. To change the denominator to 24…we had to multiply 8 by 3.

Since we multiplied the denominator by 3, we also multiply the numerator, or top number, by 3.

5 times 3 equals 15. So we changed 5/8 to 15/24.

We can because every number over itself is equal to 1.

So if we multiply 5/8 by 3/3…

So when we multiply 5/8 by 3/3, we’re really multiplying 5/8 by 1.

Since every number times 1 is equal to itself…

Since any number times 1 equals itself, we can say that 5/8 equals 15/24.

Now let’s do the same with our other fraction: 4/6. We also changed its denominator to 24.

Our old denominator was 6. To get 24, we multiplied 6 by 4.

So we also multiply the numerator by 4.

4 times 4 is 16. So 4/6 equals 16/24.

Now that the denominators are the same, we can compare the two fractions by looking at their numerators.

16/24 is greater than 15/24…

16/24 is greater than 15/24… so 4/6 is greater than 5/8.

reduce fractions

Which of these is bigger: 4/8 or 1/2?

If you did the math or just looked at the picture you might have been able to tell that they are the same. In other words, 4/8 and 1/2 mean the same thing, even though they’re spelled differently.

If 4/8 means the same as 1/2, why not just call it that? One half is easier to say than four eighths, and it’s also easier for most people to understand. After all, when dining out with a friend, split the bill in half, not eighths.

If you write 4/8 as 1/2, reduce it. When we shorten a fraction, we write it in a simpler form. Reduced fractions are always equal to the original fraction.

We have already reduced 4/8 to 1/2. If you look at the examples below, you can see that other numbers can be reduced to 1/2 as well. These fractions are all the same.

5/10 = 1/2

22.11 = 1/2

36/72 = 1/2

These fractions have also all been reduced to a simpler form.

4/12 = 1/3

14/21 = 2/3

35/50 = 7/10

Click through the slideshow to learn how to reduce fractions by dividing.

Let’s try to reduce this fraction: 16/20.

Since the numerator and denominator are even numbers, you can divide them by 2 to shorten the fraction.

First we divide the numerator by 2. 16 divided by 2 equals 8.

Next we divide the denominator by 2. 20 divided by 2 equals 10.

We reduced 16/20 to 8/10. We could also say that 16/20 equals 8/10.

If the numerator and denominator are still divisible by 2, we can further reduce the fraction.

8 divided by 2 is 4.

10 divided by 2 is 5.

Since there is no number by which 4 and 5 can be divided, we cannot reduce 4/5 any further.

This means that 4/5 is the simplest form of 16/20.

Let’s try reducing another fraction: 6/9.

While the numerator is even, the denominator is an odd number, so we can’t reduce by dividing by 2.

Instead, we need to find a number by which 6 and 9 can be divided. A multiplication table makes this number easy to find.

Let’s find 6 and 9 in the same row. As you can see, 6 and 9 can both be divided by 1 and 3.

Dividing by 1 doesn’t change these fractions, so we use the largest number that 6 and 9 can be divided by.

That’s 3. This is called the greatest common divisor, or gcd. (It can also be called the greatest common factor or GCF.)

3 is the gcd of 6 and 9 because it’s the largest number they can be divided by.

So we divide the numerator by 3. 6 divided by 3 is 2.

Then we divide the denominator by 3. 9 divided by 3 is 3.

Now we’ve reduced 6/9 to 2/3, which is the simplest form. We could also say that 6/9 equals 2/3.

Irreducible fractions

Not all fractions can be reduced. Some are already as simple as they can be. For example, you can’t cancel 1/2 because there is no number other than 1 that can divide both 1 and 2. (For this reason, you cannot reduce a fraction that has a numerator of 1.)

Also, some fractions with larger numbers cannot be reduced. For example, 17/36 cannot be reduced because there is no number by which both 17 and 36 can be divided. If you can’t find common multiples for the numbers in a fraction, it’s probably irreducible.

Try this!

Reduce each fraction to its simplest form.

Mixed numbers and improper fractions

In the previous lesson, you learned about mixed numbers. A mixed number has both a fraction and a whole number. An example is 1 2/3. You would read 1 2/3 like this: one and two thirds.

Another spelling would be 5/3 or five thirds. These two numbers look different but are actually the same. 5/3 is an improper fraction. It just means that the numerator is greater than the denominator.

There are times when you might prefer to use an improper fraction instead of a mixed number. It’s easy to convert a mixed number to an improper fraction. Let’s learn how:

Let’s convert 1 1/4 to an improper fraction.

First we need to figure out how many parts make up the whole number: 1 in this example.

To do this, we multiply the whole number , 1, by the denominator 4.

1 times 4 equals 4.

Now let’s add this number, 4, to the numerator 1.

4 plus 1 equals 5.

The denominator stays the same.

Our improper fraction is 5/4, or five quarters. So we could say that 1 1/4 equals 5/4.

This means that in 1 1/4 there are five 1/4s.

Let’s convert another mixed number: 2 2/5.

First we multiply the whole number by the denominator. 2 times 5 equals 10.

Next we add 10 to the numerator. 10 plus 2 equals 12.

The denominator remains the same as always.

So 2 2/5 equals 12/5.

Try this!

Try converting these mixed numbers to improper fractions.

Convert improper fractions to mixed numbers

Improper fractions are useful for math problems that use fractions, as you’ll learn later. However, they are also more difficult to read and understand than mixed numbers. For example, it is much easier to visualize 2 4/7 in your head than 18/7.

Click through the slideshow to learn how to convert an improper fraction to a mixed number.

Let’s turn 10/4 into a mixed number.

You can think of every fraction as a division problem. Just treat the dash between the numbers like a division sign (/).

So we divide the numerator 10 by the denominator 4.

10 divided by 4 equals 2…

10 divided by 4 gives 2… with remainder 2.

The answer 2 becomes our integer because 10 can be divided by 4 twice.

And the remainder, 2, becomes the numerator of the fraction because we have 2 parts left.

The denominator stays the same.

So 10/4 equals 2 2/4.

Let’s try another example: 33/3.

We divide the numerator 33 by the denominator 3.

33 divided by 3…

33 divided by 3…is 11 with no remainder.

The answer, 11, becomes our integer.

There’s no remainder, so we can see that our improper fraction was actually an integer. 33/3 equals 11.

Try this!

Try converting these improper fractions into mixed numbers.

It can be difficult to remember which inequality sign or symbol to use in a number comparison, but we have a simple memory trick that can help!

Notice how the inequality symbol has a wide end and a narrow end?

The wide end opens to the larger value and the narrow end points to the smaller value. If we describe the image below from left to right, it reads that all spider people are bigger (or taller) than just a spider ham.

If we flip things around, we can still read it left-to-right, but now it reads like one Spider-Ham is smaller (or smaller) than all of the Spider People.

larger number

How do we find the larger number? 🕵🏿‍♀️

The larger digit is farther from 0 on the number line. When we compare numbers, we compare place values ​​from left to right. The number that has the first place value with a on the number line. The number furthest to the right on the number line is the larger number. − 4 − 3 − 2 − 1 0 1 2 3 4 Move left Move right Remember that numbers are larger further to the right, by imagining a phone’s signal bars – the bars get bigger and stronger the further we go go right. This also means that any positive number is greater than any negative number 💡. Why is a larger negative number smaller than a smaller negative number? 🤔 Remember that as we move right on the number line, the numbers get bigger. For negative numbers, you can think of “greater than” as meaning “which number is less negative (or more positive)”. − 7 − 2 0 − 2 > − 7 Since −2 is further to the right than −7, −2 is greater than −7.

We can apply the same concept to comparing numbers. The sign should always be that

I recently read the book Beyond Pizzas & Pies: 10 Essential Strategies for Supporting Fraction Sense by Julie McNamara and Meghan Shaughnessy.

I posted the following image on Twitter while reading during my daughter’s swim class.

My colleague Hedge replied that he was challenged by a middle school teacher on this very subject.

I let them know that a few years ago, when I was a digital curriculum developer, I was also challenged for this idea. The argument I heard at the time was that using context to check the correctness of fractional comparisons would be against the fact that fractions are numbers. Therefore, 1/2 is always greater than 1/3, regardless of context. I wondered about that at the time, but I still felt it was important to show context.

Jump ahead and I’ve been thinking about this idea all day. I think I finally understand why we need to be careful about what we say about the role of context when comparing fractions. I may be completely off the mark, but I’ll still share my thoughts and let you decide in the comments whether you want to challenge my thoughts or share an alternative point of view.

Let’s start with whole numbers. If I told you to compare 3 and 6, you would probably say “3 is less than 6” or “6 is greater than 3”. This is how the numbers 3 and 6 are related.

Now what if I showed you these two pictures of 3 and 6: (As illustrated by my daughter’s toys.)

Technically the 3 dolls are bigger and therefore make up more stuff, but does that really mean that 3 is now bigger than 6? In the end, my daughter has fewer dolls (3) than figures (6). The context does not fundamentally change the relationship between the numbers 3 and 6.

In this case I don’t even know how to justify that she has more when I refer to the dolls. Sure, they’re bigger, but she might prefer to have more things to play with, and chooses the 6 figures even though they’re smaller overall.

Let’s continue by looking at this from a fractional perspective. Now I take 1/3 of the dolls and 1/2 of the figures.

Consistent with the idea that context should determine when one number is larger than another, I should be confident that 1/3 of the puppets is larger than 1/2 of the figures because 1 puppet is so much larger than the 3 characters. Oh wait, or should I be thinking that 1/2 of the figures is larger than 1/3 of the dolls because I ended up with 3 figures, which is a larger number of things than 1 doll? It’s not that clear cut, even if I try to let the context dictate how to interpret the fractions.

It boils down to breaks representing a relationship. When I think about the relationships each fraction represents, 1/2 is always greater than 1/3 no matter how I try to rotate it. Looking back at my examples, taking 1/2 of the figurine group means I’m taking a larger proportion of that group (this whole) than if I take 1/3 of the puppet group (a different whole, but still a whole) . The size of things in my group (total) doesn’t matter because the relationship represented by 1/2 is larger than the relationship represented by 1/3.

Does this mean that we should ignore contexts altogether? no There’s still a lot of debate about who ate more pizza when one person eats half of a small pizza and another person eats a third of a large pizza. Context is still interesting to discuss and helps students use math to interpret the world around them. However, if our goal is to compare fractions, then 1/2 is greater than 1/3 every time.

That’s the argument I came up with today, trying to understand the criticism I’ve heard. Now that you’ve read it, what do you think?

How to compare fractions

To compare fractions with different denominators, convert them into equivalent fractions with the same denominator.

If you have mixed numbers, convert them to improper fractions. Find the lowest common denominator (LCD) for the fractions. Convert each fraction to its equivalent using the LCD in the denominator. Compare fractions: If the denominators are the same, you can compare the numerators. The fraction with the larger numerator is the larger fraction.

Example:

Compare 5/6 and 3/8.

Find the LCD: The multiples of 6 are 6, 12, 18, 24, 30, etc. The multiples of 8 are 8, 16, 24, 32, etc. The least common multiple is 24, so we’ll use that as the least common multiple Denominator.

Convert each fraction to its corresponding fraction using the LCD.

For 5/6 numerator and denominator, multiply by 4 to have LCD = 24 in the denominator.

\( \dfrac{5}{6} \times \dfrac{4}{4} = \dfrac{20}{24} \)

For 3/8 numerator and denominator, multiply by 3 to have LCD = 24 in the denominator.

\( \dfrac{3}{8} \times \dfrac{3}{3} = \dfrac{9}{24} \)

Compare the fractions. Since there are equal denominators, you can compare the numerators. 20 is greater than 9, so:

Since \( \dfrac{20}{24} > \dfrac{9}{24} \) we conclude \( \dfrac{5}{6} > \dfrac{3}{8} \)

First, take both sets and compare which one is larger. Then write them into a subtraction equation and evaluate them using the LCM method or by cross-multiplying the fractions and then subtracting the second number from the first to get the numerator part and multiplying the denominators to get a common denominator . Given quantities are 1$$ inch and $\dfrac{3}{8}$ inch. If we compare the sets, we can say that $1 > \dfrac{3}{8}$Since we need to find out how much of the first set is left after removing As the second quantity, we write a subtraction equation.$ \Rightarrow 1 – \dfrac{3}{8}$We can write $1$ in fractional form as $\dfrac{1}{1}$, we can rewrite the equation as ,$ \Rightarrow \dfrac{1}{1} – \ dfrac{3}{8}$Now multiply the fractions, then subtract the numerators, then multiply the denominators to get a common denominator.$ \Rightarrow \dfrac{ {(1 \times 8) – (3 \ times 1)}}{{(1 \times 8)}}$If evaluated further,$ \Rightarrow \dfrac{{8 – 3}}{8}$What is equal to,$ \Rightarrow \dfrac{5}{ 8}$Whenever there are different denominators in a subtraction equation, the first step must be to transform them so that they have the same denominators.

The table below can be used to easily find the correct fraction for your decimal measurement, or vice versa. Find decimal equivalents in 1⁄ 64 inch increments, including 1⁄ 2, 1⁄ 4, 1⁄ 8, 1⁄ 16, and 1⁄ 32 inch measurements.

The table also shows indications of marking sizes on a tape measure or ruler.

How to Calculate Fractional Customs

Fractions of inches use denominators that are powers of 2 and go up to 64ths of an inch. This means that the denominators of the fractions are 2, 4, 8, 16, 32, and 64. Therefore, converting a decimal to a fraction of an inch is not quite the same as converting a decimal to a regular fraction.

Instead, it is necessary to find the nearest fraction with the denominator that is a power of 2, also known as a dyadic fraction or dyadic rational number.[1] Typical inch fractions look something like 1/64, 1/32, 1/16, 1/8, 1/4, or 1/2. Use our feet and inches calculator to add or subtract fractions of feet and inches.

How to convert inches to fractions

To convert a decimal inch to a fractional inch, you must round the decimal part to the nearest fractional inch.

Separate the integer from the decimal; that’s all the inches. Then take the remaining part of the decimal place to the right of the decimal point and multiply it by the precision you need (e.g. 1/16, 1/32 or 1/64).

For example, to round to the nearest 1/16, take the decimal part and multiply it by 16. Then round it to get the numerator of the fractional inch.

Finally, place the numerator above the precision level, in this case 16. Then put the fractional inches next to the whole inches to get the final result.

For example, let’s convert 2.695 inches to a fraction with a precision of 1/16″. Remove the integer 2 from the decimal to get the decimal 0.695. Then multiply 0.695 by 16. 0.695 × 16 = 11.12 Round this to the nearest whole number; In this case, 11.12 can be rounded to 11. Put that in a fraction above 16, so 11/16 is the remaining fraction of an inch. Put everything together by placing the whole inch (2) before the fractional inch. 2.695 inches = 2 11/ 16 So using this method you can see that 2.695 decimal inches equals 2 11/ 16 as a fractional inch.

Find fractions in inches on a tape measure

Finding measurements on a ruler or tape measure can be confusing at first, but once you understand how the markings are laid out, it’s a lot easier. The markings between the larger inch numbers vary in length.

The longest marks are the quarter inch marks, i. H. the first mark is 1/4 inch, the second 1/2 (2/4) inch, the third 3/4 inch.

The next longest marks are the eighths of an inch marks, i. H. the first mark is 1/8 inch, the second 3/8 inch, the third 5/8 inch, etc.

The next longest marks are the sixteenth inch marks, i. H. the first mark is 1/16 inch, the second 3/16 inch, the third 5/16 inch, etc.
