How to work it out
- Turn the percentage into a decimal: 72 ÷ 100 = 0.72
- Multiply: 0.72 × 31 = 22.32
- Check: Work backwards: 22.32 ÷ 31 × 100 = 72%.
Another method. As a proportion of part to whole: 72/100 = part/31, so part = 72 × 31 ÷ 100 = 22.32. Both methods always give the same answer.
In a spreadsheet: =72%*31. 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 72%
Increasing 31 by 72% gives 53.32 and decreasing it by 72% gives 8.68. These do not cancel out: raising 31 by 72% and then lowering the result by 72% ends at 14.9296, because the second 72% is taken of a bigger number.
