Here is our Simplify Fraction Calculator which will show you how to simplify fractions. The calculator will also show you step-by-step working out so you can see all the required steps.

To enter a fraction, you have to enter the numerator followed by '/' followed by the denominator. E.g. 4/5 or 23/7

To enter a mixed fraction, first type the whole number followed by space followed by the numerator followed by '/' followed by the denominator.

E.g. 3 1/4 (3 and a quarter), 7 2/5 (seven and two-fifths), 10 4/11 (10 and four-elevenths).

If you need to find out how to simplify a fraction, there is more help further down!

Please Note:

There are other ways that you find a fraction's simplest form without needing to find the highest common factor (or greatest common divisor) simply by finding any common factor and canceling it out.

You then have to repeat this finding and canceling common factors until only '1' is left as a common factor.

Your fraction is then in its simplest form.

Take a look at our NEW Simplifying Fractions Practice Zone for finding the simplest form for a range of fractions.

You can choose from proper fractions, improper fractions or both.

You can print out your results or benchmark your scores against future achievements.

Great for using with a group of children as well as individually.

We also have a support page about how to simplify fractions which will take you through the process step-by-step.

There are several worked examples and also some practice sheets with answers.
