Go straight to resources ↓One percent is one part out of a hundred
Percentages describe a proportion, not a fixed count. Identify what represents 100%, then take the required number of hundredths.
| Proportion | Meaning | Amount |
|---|---|---|
| 100 % | the whole base | 200 |
| 1 % | one hundredth of the base | 2 |
| 25 % | 25 hundredths of the base | 50 |
One worked example
- 25 % = 25/100 = 1/425 out of 100 is the same proportion as one quarter.
- 200 ÷ 100 = 2Divide 200 by a hundred to find one percent.
- 25 × 2 = 50Twenty-five of these parts make 50.
Watch out: For a discount, this finds the amount removed. Finding the discounted price also requires subtracting it from the original price.
