How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 38 = 11.78
  3. Check: Work backwards: 11.78 ÷ 38 × 100 = 31%.

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

In a spreadsheet: =31%*38. 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 31% share of 38. The remaining 69% is 26.22, and the two parts add back up to 38.

Discounts: 31% off an item priced $38 saves $11.78, so you pay $26.22.

Adding and taking away 31%

Increasing 38 by 31% gives 49.78 and decreasing it by 31% gives 26.22. These do not cancel out: raising 38 by 31% and then lowering the result by 31% ends at 34.3482, because the second 31% is taken of a bigger number.
