How to work it out
- Turn the percentage into a decimal: 57 ÷ 100 = 0.57
- Multiply: 0.57 × 15 = 8.55
- Check: Work backwards: 8.55 ÷ 15 × 100 = 57%.
Another method. As a proportion of part to whole: 57/100 = part/15, so part = 57 × 15 ÷ 100 = 8.55. Both methods always give the same answer.
In a spreadsheet: =57%*15. 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
8.55 is the 57% share of 15. The remaining 43% is 6.45, and the two parts add back up to 15.

Adding and taking away 57%
Increasing 15 by 57% gives 23.55 and decreasing it by 57% gives 6.45. These do not cancel out: raising 15 by 57% and then lowering the result by 57% ends at 10.1265, because the second 57% is taken of a bigger number.
