How to work it out

  1. Turn the percentage into a decimal: 27 ÷ 100 = 0.27
  2. Multiply: 0.27 × 15 = 4.05
  3. Check: Work backwards: 4.05 ÷ 15 × 100 = 27%.

Another method. As a proportion of part to whole: 27/100 = part/15, so part = 27 × 15 ÷ 100 = 4.05. Both methods always give the same answer.

In a spreadsheet: =27%*15. 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

4.05 is the 27% share of 15. The remaining 73% is 10.95, and the two parts add back up to 15.

Discounts: 27% off an item priced $15 saves $4.05, so you pay $10.95.

Adding and taking away 27%

Increasing 15 by 27% gives 19.05 and decreasing it by 27% gives 10.95. These do not cancel out: raising 15 by 27% and then lowering the result by 27% ends at 13.9065, because the second 27% is taken of a bigger number.
