How to work it out

  1. Turn the percentage into a decimal: 38 ÷ 100 = 0.38
  2. Multiply: 0.38 × 31 = 11.78
  3. Check: Work backwards: 11.78 ÷ 31 × 100 = 38%.

Another method. As a proportion of part to whole: 38/100 = part/31, so part = 38 × 31 ÷ 100 = 11.78. Both methods always give the same answer.

In a spreadsheet: =38%*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

11.78 is the 38% share of 31. The remaining 62% is 19.22, and the two parts add back up to 31.

Discounts: 38% off an item priced $31 saves $11.78, so you pay $19.22.

Adding and taking away 38%

Increasing 31 by 38% gives 42.78 and decreasing it by 38% gives 19.22. These do not cancel out: raising 31 by 38% and then lowering the result by 38% ends at 26.5236, because the second 38% is taken of a bigger number.
