How to work it out
- Turn the percentage into a decimal: 31 ÷ 100 = 0.31
- Multiply: 0.31 × 91 = 28.21
- Check: Work backwards: 28.21 ÷ 91 × 100 = 31%.
Another method. As a proportion of part to whole: 31/100 = part/91, so part = 31 × 91 ÷ 100 = 28.21. Both methods always give the same answer.
In a spreadsheet: =31%*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 31%
Increasing 91 by 31% gives 119.21 and decreasing it by 31% gives 62.79. These do not cancel out: raising 91 by 31% and then lowering the result by 31% ends at 82.2549, because the second 31% is taken of a bigger number.
