How to work it out

  1. Turn the percentage into a decimal: 83 ÷ 100 = 0.83
  2. Multiply: 0.83 × 15 = 12.45
  3. Check: Work backwards: 12.45 ÷ 15 × 100 = 83%.

Another method. As a proportion of part to whole: 83/100 = part/15, so part = 83 × 15 ÷ 100 = 12.45. Both methods always give the same answer.

In a spreadsheet: =83%*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

12.45 is the 83% share of 15. The remaining 17% is 2.55, and the two parts add back up to 15.

Discounts: 83% off an item priced $15 saves $12.45, so you pay $2.55.

Adding and taking away 83%

Increasing 15 by 83% gives 27.45 and decreasing it by 83% gives 2.55. These do not cancel out: raising 15 by 83% and then lowering the result by 83% ends at 4.6665, because the second 83% is taken of a bigger number.
