How to work it out

  1. Turn the percentage into a decimal: 38 ÷ 100 = 0.38
  2. Multiply: 0.38 × 45 = 17.1
  3. Check: Work backwards: 17.1 ÷ 45 × 100 = 38%.

Another method. As a proportion of part to whole: 38/100 = part/45, so part = 38 × 45 ÷ 100 = 17.1. Both methods always give the same answer.

In a spreadsheet: =38%*45. 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

17.1 is the 38% share of 45. The remaining 62% is 27.9, and the two parts add back up to 45.

Discounts: 38% off an item priced $45 saves $17.1, so you pay $27.9.

Adding and taking away 38%

Increasing 45 by 38% gives 62.1 and decreasing it by 38% gives 27.9. These do not cancel out: raising 45 by 38% and then lowering the result by 38% ends at 38.502, because the second 38% is taken of a bigger number.
