Percentage of an Amount — Free KS3 Worksheet

A free, printable KS3 worksheet on finding a percentage of an amount without a calculator, with a full worked answer key. 16 questions graded easy to hard for Years 7, 8 and 9, including word problems.

Practise finding a percentage of an amount without a calculator. Start by finding 10% — just divide by 10 — then build up: 30% is three lots of 10%, and 5% is half of 10%, so 15% is 10% plus 5%. The questions build from simple multiples of 10% up to word problems with money and discounts, and every one comes with a full worked answer so you can mark it together.
