How to work it out

  1. Turn the percentage into a decimal: 79 ÷ 100 = 0.79
  2. Multiply: 0.79 × 15 = 11.85
  3. Check: Work backwards: 11.85 ÷ 15 × 100 = 79%.

Another method. As a proportion of part to whole: 79/100 = part/15, so part = 79 × 15 ÷ 100 = 11.85. Both methods always give the same answer.

In a spreadsheet: =79%*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

11.85 is the 79% share of 15. The remaining 21% is 3.15, and the two parts add back up to 15.

Discounts: 79% off an item priced $15 saves $11.85, so you pay $3.15.

Adding and taking away 79%

Increasing 15 by 79% gives 26.85 and decreasing it by 79% gives 3.15. These do not cancel out: raising 15 by 79% and then lowering the result by 79% ends at 5.6385, because the second 79% is taken of a bigger number.
