Percentages are a way of representing parts of numbers, similar to fractions or decimals. For your Eleven Plus maths exam you will have to calculate percentages. If you haven’t mastered it yet then don’t worry – this quiz will show you how to do it.
Let’s give you an example:
What is 25% of 90? Well, first of all, divide 90 by 100 to work out 1% of 90:
90 ÷ 100 = 0.9
We want to find 25% of 90 so next we multiply 0.9 by 25:
0.9 x 25 = 22.5 so, 25% of 90 is 22.5.
I hope that’s made things easier to understand. Have a go at this quiz and (if you haven’t already) play our other quizzes on percentages. The more you practise, the easier they will be.
DON'T forget: when you divide by 100, move the digits two places to the right
