Education & Reference / How to Divide Fractions

In fact, there are several ways of dividing fractions and we will explain you the two easiest ones.

Inverting and Multiplying

In order to divide fractions, using this method, do the following:

- First of all, you have to invert the fraction (just flip it over) of the divisor. You will get what is called "the reciprocal"
^{2}. E.g. 2/5 becomes 5/2. - Multiply the fractions. We hope you know how to multiply fractions. All you have to do is to multiply the denominators3 and numerators
^{4}. - If possible, convert them to a mixed number. E.g. 13/8 will be 1 5/8.

For example: 2/3÷2/5 = 2/3*5/2 = 10/6 = 1 4/6 = 1 2/3

Common Denominator

Another way of dividing fractions is using a common denominator. This method is lengthier but it can be more useful in everyday life. It includes the following steps:

- You should find a common denominator. Then you need to convert the fractions to the equivalent value.
- Now then the denominators are equal it is possible to divide the numerators.

E.g.: 4/5÷2/3 = 12/15÷10/15 = 12/10 = 1 1/5

Now you know two ways of dividing fractions. If you are going to teach your child how to divide a fraction by a fraction, you should better explain him the first method, because it is really much easier.
