Percentages worksheet

Percent of a number and what percent one number is of another. Harder sets add percent change and discounts. Free, printable, and the answer key prints on its own page, so the work comes first.

How to solve them

1. Turn the percent into a decimal first: 15% is 0.15.
2. Percent of a number: multiply. What percent: divide the part by the whole, times 100.
3. Percent change: (new − old) ÷ old, times 100. A discount takes that percent off the price.

New to this? The short lesson on it has the rules in one place.

Check the key only once you've finished. A wrong answer is useful: find the first line where your working went wrong, fix that, and redo the problem.
