Year 8 Percentages worksheets for year 8 maths, or class 8. Children in year 8 are age between 12 and 13. Each year 8 Percentages worksheet is differentiated and covers key stage 3. In year 8 students practice mental percentages, percentage of amounts, spider diagrams and calculator methods across a range of differentiated worksheets. Students might be familiar from year 7 maths worksheets, that to find 10% you divide by 10; to work out 25% you divide by 4 and to work out 50% you divide by 2.

Here's the trick, once you work out 10% you can easily find 20%, 30%, 40% and so on: you multiply the value of 10% by 2 to get 20%, by 3 to get 30% and by 4 to get 40%, and so on. For example 10% of 30 is 3 because 30 ÷ 10 = 3. 20% of 30 is 6 because 3 x 2 = 6. 30% of 30 is 9 because 3 x 3 = 9 and 40% of 30 is 12 because 4 x 3 = 12. What is 25% of 30?
