The strategy
How it works
Match the percentage to a fraction: 50% = 1/2, 25% = 1/4, 75% = 3/4.
Divide the amount by the fraction denominator.
For 75%, take three of the quarter-sized parts.

Worked examples
Example 125% of 80
- 25% is one quarter.
- 80 ÷ 4 = 20.
- So 25% of 80 is 20.
Answer: 20
Example 275% of 40
- 25% of 40 is 10.
- 75% is three lots of 25%.
- 3 × 10 = 30.
Answer: 30
A quick heads-up
Common mistakes to avoid
- Dividing by 25 instead of by 4 to find 25%; one quarter is the amount divided into four equal parts.
- Finding 25% for 75% and stopping; take three quarters, not one.
