# Level 3-4 Numbers - Fractions - Simplification

Fractions of numbers are an important part of KS3 Maths. Fractions can be written more than one way. For instance, ten twentieths could be written as ^{10}⁄_{20}. But ^{10}⁄_{20} has the same value as ^{2}⁄_{4} or ^{1}⁄_{2}. Writing fractions in simpler forms like this is called simplification.

Simplification of a fraction means looking for the highest common factor on the top and bottom of it. Using the above example, in ^{10}⁄_{20} the highest common factor of 10 and 20 is 10. Divide each of the numbers by 10 and you get 1 and 2. So, in its simplest form ^{10}⁄_{20} is ^{1}⁄_{2}. Remember to look for the highest common factors in fractions and you'll soon find simplification is simple!

Practise is the best way to familiarise yourself with something. So, by the time you've finished this quiz, you'll be a dab hand! Take your time, read each question carefully and consider your answers. And don't forget the helpful comments after each question. They can help to explain things and make them a little clearer.
