Worked example
25% of 80
Answer: 20
How to solve it
25% equals one quarter. Divide 80 into four equal parts: 80 / 4 = 20. Equivalently, 0.25 x 80 = 20.
Common mistakes
What to check
- using the percent as a whole number instead of a decimal
- finding the discount but not the sale price
Ways to review the work
- 1
Estimate with 10%, 25%, or 50% benchmarks before calculating exactly.
- 2
Ask whether a 25% portion should be larger or smaller than half the original amount.
