Key takeaways

Fractions are already parts of a whole number. So, you might be wondering: how can you divide a fraction into an even smaller part—or, for that matter, divide it to turn it into an even bigger part? 

Honestly, it works the same way dividing whole numbers works. You can divide a small number into an even smaller number, right? 4 divided by 2 gives you 2. So how can ¼ divided by ½ give you ½? Today, we’re going to walk through how to divide fractions in 5 easy steps. But first, let’s make sure we understand the basics to make it super easy to follow along.

The parts of a fraction

Unlike a whole number, a fraction has two parts. 

  • The numerator – This is the number on the top of the fraction. If you think of a fraction as shaded parts of a whole, it is how many sections you would shade in. 
  • The denominator – This is the number on the bottom of the fraction. So, using the example of a fraction as shaded parts of a whole, it would be how many sections available to shade in. 

 

Visually, 1/4 would look like this, with 1 out of 4 parts shaded in.

And 3/16 would look like this, with 3 out of 16 parts shaded in.

Dividing fractions, step by step

There are several different ways to divide fractions, but if you try to master them or use them all at once, it might get super confusing. It’s always best to divide complicated ideas into smaller parts to make the ideas easier to understand. Let’s DIVIDE (ha, see what we did there?) dividing fractions into 5 easy steps to help make it easier.

1. Read the problem

It might sound simple, but first, you need to understand what you’re being asked to do. Let’s look at the following problem:

Basically, you’re being asked to divide five-sixths by seven-eighths. 

2. Keep the first fraction as is

Next, you need to know what to do with each of the fractions in the problem. Do not do anything to the first fraction. Keep it EXACTLY as it is.

3. Change the division sign to a multiplication sign

You mean I have to know how to multiply to know how to divide? Absolutely you do! What you want to do in this step is to change the DIVISION sign to a MULTIPLICATION sign. 

So, if we were just rewriting the problem and this was our final step, the problem would look like this: 

But it ISN’T the last step. The last step is…

4. Flip the second fraction

The last step before you can solve the problem is to flip the numerator with the denominator in the second fraction. So, now your problem looks like this: 

5. Solve by multiplying the numerators and denominators together, then simplify if necessary

The answer is 16/9, which cannot be simplified, so it remains the same.

The answer is 15/6, and since both 15 and 6 can be divided by 3, the answer, when simplified, will be 5/2.

The answer is 16/15. This cannot be simplified, as these numbers cannot be divided by a similar number.

The answer is 4/3. This is simplified from 24/18, numbers that can each be divided by 6 to give you 4/3.

The answer is 12/7. This cannot be simplified, as these numbers cannot be divided by a similar number.

The answer is 7/4, simplified from 14/8, which can both be divided by 2 to give you the answer.

FAQs about dividing fractions

To divide fractions, you multiply the first fraction by the reciprocal (flipped version) of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and denominator. For example, to divide 1/2 by 3/4, you multiply 1/2 by 4/3. The result is (1/2) × (4/3) = 4/6, which simplifies to 2/3.

If the divisor is a whole number, you can convert it to a fraction by putting it over 1. For example, if you want to divide 3/4 by 2, you can rewrite it as 3/4 ÷ 2/1. Then, you proceed with the division using the reciprocal: (3/4) × (1/2) = 3/8.

Yes, the dividend can be a whole number! In division, the whole number is treated as a fraction with a denominator of 1. For example, if you want to divide 2 by 3/4, you can rewrite it as 2/1 ÷ 3/4. Then, you proceed with the division using the reciprocal: (2/1) × (4/3) = 8/3.

To simplify the result, reduce the fraction to its simplest form by dividing both the numerator and denominator by their greatest common divisor. For example, if the result of dividing fractions is 12/16, you can simplify it by dividing both the numerator and denominator by 4. The simplified form is 3/4.
