How to work it out
- Turn the percentage into a decimal: 64 ÷ 100 = 0.64
- Multiply: 0.64 × 31 = 19.84
- Check: Work backwards: 19.84 ÷ 31 × 100 = 64%.
Another method. As a proportion of part to whole: 64/100 = part/31, so part = 64 × 31 ÷ 100 = 19.84. Both methods always give the same answer.
In a spreadsheet: =64%*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 64%
Increasing 31 by 64% gives 50.84 and decreasing it by 64% gives 11.16. These do not cancel out: raising 31 by 64% and then lowering the result by 64% ends at 18.3024, because the second 64% is taken of a bigger number.
