How to work it out
- Turn the percentage into a decimal: 15 ÷ 100 = 0.15
- Multiply: 0.15 × 91 = 13.65
- Check: Work backwards: 13.65 ÷ 91 × 100 = 15%.
Another method. As a proportion of part to whole: 15/100 = part/91, so part = 15 × 91 ÷ 100 = 13.65. Both methods always give the same answer.
In a spreadsheet: =15%*91. 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 91 by 15% gives 104.65 and decreasing it by 15% gives 77.35. These do not cancel out: raising 91 by 15% and then lowering the result by 15% ends at 88.9525, because the second 15% is taken of a bigger number.
