Percentages

Clear, approachable guidance with examples you can apply in everyday situations.

Take your time with each concept. Try a small example, explain the steps, and check whether the result makes sense.

Remember what percent means

Percent means per hundred, so 25% is 25 out of 100, or one quarter.

To find 10% of a value, divide it by 10; other percentages can be built from useful parts.

Check the original amount and the unit before comparing percentage changes or discounts.

Return to the basics whenever a step feels unclear, and use estimates to check that your answer is reasonable.
