Worksheet Overview

This activity is about calculating a percentage of an amount.

Percentages are great because they help us to compare things which are not out of the same number!

Let's say that a student gets 34/47 in maths  and   23/34 in English.

We can compare them if we know the percentages:

Maths 72%          English 68%

Now we can see that the student has done better in maths!


To find the percentage of an amount, it always helps to know 10% because it can be used for finding others.

Let's look at a question.



Calculate 10% of £30. 



To find 10%, it is one tenth of the amount, so we divide by 10.

Therefore, 30 ÷ 10 = £3


To find 20% we can simply double 10%.

Therefore, £3 x 2 = £6


Let's try some questions now.
