How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 10 = 3.1
  3. Check: Work backwards: 3.1 ÷ 10 × 100 = 31%.

Another method. As a proportion of part to whole: 31/100 = part/10, so part = 31 × 10 ÷ 100 = 3.1. Both methods always give the same answer.

In a spreadsheet: =31%*10. 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

3.1 is the 31% share of 10. The remaining 69% is 6.9, and the two parts add back up to 10.

Discounts: 31% off an item priced $10 saves $3.1, so you pay $6.9.

Adding and taking away 31%

Increasing 10 by 31% gives 13.1 and decreasing it by 31% gives 6.9. These do not cancel out: raising 10 by 31% and then lowering the result by 31% ends at 9.039, because the second 31% is taken of a bigger number.
