How to work it out

  1. Turn the percentage into a decimal: 90 ÷ 100 = 0.9
  2. Multiply: 0.9 × 38 = 34.2
  3. Check: Work backwards: 34.2 ÷ 38 × 100 = 90%.

Another method. As a proportion of part to whole: 90/100 = part/38, so part = 90 × 38 ÷ 100 = 34.2. Both methods always give the same answer.

In a spreadsheet: =90%*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

34.2 is the 90% share of 38. The remaining 10% is 3.8, and the two parts add back up to 38.

Discounts: 90% off an item priced $38 saves $34.2, so you pay $3.8.

Adding and taking away 90%

Increasing 38 by 90% gives 72.2 and decreasing it by 90% gives 3.8. These do not cancel out: raising 38 by 90% and then lowering the result by 90% ends at 7.22, because the second 90% is taken of a bigger number.
