How to work it out
- Turn the percentage into a decimal: 68 ÷ 100 = 0.68
- Multiply: 0.68 × 31 = 21.08
- Check: Work backwards: 21.08 ÷ 31 × 100 = 68%.
Another method. As a proportion of part to whole: 68/100 = part/31, so part = 68 × 31 ÷ 100 = 21.08. Both methods always give the same answer.
In a spreadsheet: =68%*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
21.08 is the 68% share of 31. The remaining 32% is 9.92, and the two parts add back up to 31.

Adding and taking away 68%
Increasing 31 by 68% gives 52.08 and decreasing it by 68% gives 9.92. These do not cancel out: raising 31 by 68% and then lowering the result by 68% ends at 16.6656, because the second 68% is taken of a bigger number.
