I always found this to be a sticking point at school and this is how I teach my GCSE students. To make it easier, think about it with this example: You’ve completed a test. The total marks available was 65. Let’s say you scored 54. To work out your percentage you must divide your score by the total available marks. Then multiply the answer by 100 to provide the percentage. 1. 54/65 = 0.83 (2 d.p.) 2. 0.83 x 100 = 83% Hope this helps!

Divide the number by 100 then times it by the percentage. So 20% of 200 will be: 200 / 100 = 2 2 x 20 = 40 Answer is 40
