How to work it out

  1. Turn the percentage into a decimal: 72 ÷ 100 = 0.72
  2. Multiply: 0.72 × 15 = 10.8
  3. Check: Work backwards: 10.8 ÷ 15 × 100 = 72%.

Another method. As a proportion of part to whole: 72/100 = part/15, so part = 72 × 15 ÷ 100 = 10.8. Both methods always give the same answer.

In a spreadsheet: =72%*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

10.8 is the 72% share of 15. The remaining 28% is 4.2, and the two parts add back up to 15.

Discounts: 72% off an item priced $15 saves $10.8, so you pay $4.2.

Adding and taking away 72%

Increasing 15 by 72% gives 25.8 and decreasing it by 72% gives 4.2. These do not cancel out: raising 15 by 72% and then lowering the result by 72% ends at 7.224, because the second 72% is taken of a bigger number.
