How to work it out
- Turn the percentage into a decimal: 31 ÷ 100 = 0.31
- Multiply: 0.31 × 39 = 12.09
- Check: Work backwards: 12.09 ÷ 39 × 100 = 31%.
Another method. As a proportion of part to whole: 31/100 = part/39, so part = 31 × 39 ÷ 100 = 12.09. Both methods always give the same answer.
In a spreadsheet: =31%*39. 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 31% share of 39. The remaining 69% is 26.91, and the two parts add back up to 39.

Adding and taking away 31%
Increasing 39 by 31% gives 51.09 and decreasing it by 31% gives 26.91. These do not cancel out: raising 39 by 31% and then lowering the result by 31% ends at 35.2521, because the second 31% is taken of a bigger number.
