Welcome to the second of our difficult Eleven Plus maths quizzes on percentages. In the first, you were asked to express one number as a percentage (or proportion) of another – I hope you didn’t find it too hard! In this quiz, we’ll offer you more chance to practice.
There is a simple way to do it. Here’s an example:
What percentage of 20 is 4?
First, arrange the problem like this :
(4 ÷ 20) × 100%
Next, you can make it easier by turning it around, like this:
(4 × 100) ÷ 20
Work out the part in brackets:
400 ÷ 20
This gives you the answer = 20%
Just follow this formula and percentages should be simple. So, now you are ready, let’s begin. Good luck!
