How to work it out

  1. Turn the percentage into a decimal: 77 ÷ 100 = 0.77
  2. Multiply: 0.77 × 15 = 11.55
  3. Check: Work backwards: 11.55 ÷ 15 × 100 = 77%.

Another method. As a proportion of part to whole: 77/100 = part/15, so part = 77 × 15 ÷ 100 = 11.55. Both methods always give the same answer.

In a spreadsheet: =77%*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

11.55 is the 77% share of 15. The remaining 23% is 3.45, and the two parts add back up to 15.

Discounts: 77% off an item priced $15 saves $11.55, so you pay $3.45.

Adding and taking away 77%

Increasing 15 by 77% gives 26.55 and decreasing it by 77% gives 3.45. These do not cancel out: raising 15 by 77% and then lowering the result by 77% ends at 6.1065, because the second 77% is taken of a bigger number.
