How to work it out
- Turn the percentage into a decimal: 57 ÷ 100 = 0.57
- Multiply: 0.57 × 31 = 17.67
- Check: Work backwards: 17.67 ÷ 31 × 100 = 57%.
Another method. As a proportion of part to whole: 57/100 = part/31, so part = 57 × 31 ÷ 100 = 17.67. Both methods always give the same answer.
In a spreadsheet: =57%*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 57%
Increasing 31 by 57% gives 48.67 and decreasing it by 57% gives 13.33. These do not cancel out: raising 31 by 57% and then lowering the result by 57% ends at 20.9281, because the second 57% is taken of a bigger number.
