How to work it out

  1. Turn the percentage into a decimal: 45 ÷ 100 = 0.45
  2. Multiply: 0.45 × 38 = 17.1
  3. Check: Work backwards: 17.1 ÷ 38 × 100 = 45%.

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

In a spreadsheet: =45%*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

17.1 is the 45% share of 38. The remaining 55% is 20.9, and the two parts add back up to 38.

Discounts: 45% off an item priced $38 saves $17.1, so you pay $20.9.

Adding and taking away 45%

Increasing 38 by 45% gives 55.1 and decreasing it by 45% gives 20.9. These do not cancel out: raising 38 by 45% and then lowering the result by 45% ends at 30.305, because the second 45% is taken of a bigger number.
