How to work it out
- Turn the percentage into a decimal: 15 ÷ 100 = 0.15
- Multiply: 0.15 × 57 = 8.55
- Check: Work backwards: 8.55 ÷ 57 × 100 = 15%.
Another method. As a proportion of part to whole: 15/100 = part/57, so part = 15 × 57 ÷ 100 = 8.55. Both methods always give the same answer.
In a spreadsheet: =15%*57. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.
What the result means

Adding and taking away 15%
Increasing 57 by 15% gives 65.55 and decreasing it by 15% gives 48.45. These do not cancel out: raising 57 by 15% and then lowering the result by 15% ends at 55.7175, because the second 15% is taken of a bigger number.
