How to work it out

  1. Turn the percentage into a decimal: 38 ÷ 100 = 0.38
  2. Multiply: 0.38 × 40 = 15.2
  3. Check: Work backwards: 15.2 ÷ 40 × 100 = 38%.

Another method. As a proportion of part to whole: 38/100 = part/40, so part = 38 × 40 ÷ 100 = 15.2. Both methods always give the same answer.

In a spreadsheet: =38%*40. 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

15.2 is the 38% share of 40. The remaining 62% is 24.8, and the two parts add back up to 40.

Discounts: 38% off an item priced $40 saves $15.2, so you pay $24.8.

Adding and taking away 38%

Increasing 40 by 38% gives 55.2 and decreasing it by 38% gives 24.8. These do not cancel out: raising 40 by 38% and then lowering the result by 38% ends at 34.224, because the second 38% is taken of a bigger number.
