how to convert a fraction into its simplest form.

We have a simplify fraction calculator which will convert any fraction into its simplest form.

The calculator will also show you detailed working out to show how to get the answer.

This short video clip will show you how to reduce 4 different fractions into simplest form.

Here you will find some simple information and advice about how to simplify a fraction.

At the bottom of this page you will also find a printable resource sheet and some practice sheets which will help you understand and practice this math skill.

Using these sheets will help your child to:

- understand simplest form;
- develop their knowledge of equivalent fractions.

All the Printable Fraction sheets in this section support Elementary Math Benchmarks for 4th Grade.

To simplify a fraction, you need to follow the 2 steps below:

Step 1

Look for a common factor of both the numerator and denominator.

- If there are no common factors (other than 1) then the fraction is already in its simplest form and you have finished.
- Try to find the highest factor of both numbers (highest common factor) that you can!

Step 2

Reduce the numerator and denominator by dividing them both by the common factor. Now go back to Step 1.

Your fraction should now be in its simplest form.

Example 1) Convert
35
45
to simplest form.
*

A common factor of both numbers is 5, so we need to divide the numerator and denominator by 5. This gives us:

35 ÷ 5 45 ÷ 5 = 7 9

There are no more common factors (except 1) and so this fraction is now in simplest form.

*
Example 2) Convert
68
220
into simplest form.
*

A common factor of both numbers is 2. Dividing the numerator and denominator by 2 gives us:

68 ÷ 2 220 ÷ 2 = 34 110

We are not finished yet, because 2 is a common factor of both numbers.

34 ÷ 2 110 ÷ 2 = 17 55

There are no more common factors (except 1) and so this fraction is now in simplest form.
