How to work it out
- Turn the percentage into a decimal: 39 ÷ 100 = 0.39
- Multiply: 0.39 × 31 = 12.09
- Check: Work backwards: 12.09 ÷ 31 × 100 = 39%.
Another method. As a proportion of part to whole: 39/100 = part/31, so part = 39 × 31 ÷ 100 = 12.09. Both methods always give the same answer.
In a spreadsheet: =39%*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
12.09 is the 39% share of 31. The remaining 61% is 18.91, and the two parts add back up to 31.

Adding and taking away 39%
Increasing 31 by 39% gives 43.09 and decreasing it by 39% gives 18.91. These do not cancel out: raising 31 by 39% and then lowering the result by 39% ends at 26.2849, because the second 39% is taken of a bigger number.
