### How to add and subtract fractions

In this video from KS2 Maths an astronaut finds out whether they have enough fuel by adding and subtracting fractions.

### Common denominators

It's easy to add and subtract fractions when the numbers on the bottom are the same.

These are called the denominators.

### Equivalent fractions

However, sometimes the denominators are different.

You use equivalent fractions to make them the same.

A common multiple of 2 and 3 is 6.

So, for each fraction we need an equivalent fraction with a denominator of 6.

Now you can add these together.
