How to work it out

  1. Turn the percentage into a decimal: 40 ÷ 100 = 0.4
  2. Multiply: 0.4 × 38 = 15.2
  3. Check: Work backwards: 15.2 ÷ 38 × 100 = 40%.

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

In a spreadsheet: =40%*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

15.2 is the 40% share of 38. The remaining 60% is 22.8, and the two parts add back up to 38.

Discounts: 40% off an item priced $38 saves $15.2, so you pay $22.8.

Adding and taking away 40%

Increasing 38 by 40% gives 53.2 and decreasing it by 40% gives 22.8. These do not cancel out: raising 38 by 40% and then lowering the result by 40% ends at 31.92, because the second 40% is taken of a bigger number.
