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.
Per cent means per hundred, so a percentage of an amount is a fraction of it with a hundred underneath. There are two reliable routes. Find one per cent by dividing by a hundred and then multiply, or build the answer from parts you already know, since ten per cent is a tenth and five per cent is half of that. Both are on this sheet, because different questions suit different routes.
What is on the sheet
The friendly percentages first, ten and twenty five and fifty, where the fraction is obvious and the arithmetic is quick. Then percentages that need the one per cent method. Then amounts that are not round numbers, which is where the method has to be trusted rather than eyeballed. Word problems finish it: money off a coat, how many of a group walk to school, and the size of an increase on a bill.
Marking it
The percentage of an amount lesson shows both routes on the same question so a pupil can pick the one that suits the numbers.
