Fractions I Summary

GCSE Maths

Fractions are about dividing things up into different amounts.

Fractions are written one number above the other, with a line between them, like this: ¾ = three quarters.

The top number is called the numerator.
The bottom number is the denominator.

Fractions can often represent the same amount: these are called equivalent fractions.
e.g. 5/10 = 1/2 = 60/120

Fractions can sometimes be simplified so that the numbers used are smaller.

Simplifying fractions needs you to spot common factors. Once found, you can divide by it on both the top and bottom.

Simplifying with the highest common factor is the quickest way of doing it!

If both top and bottom numbers are even, divide by 2 to help you out!

With fractions, you can have your cake and eat it!
