How to work it out

  1. Turn the percentage into a decimal: 15 ÷ 100 = 0.15
  2. Multiply: 0.15 × 83 = 12.45
  3. Check: Work backwards: 12.45 ÷ 83 × 100 = 15%.

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

In a spreadsheet: =15%*83. 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 15% share of 83. The remaining 85% is 70.55, and the two parts add back up to 83.

Discounts: 15% off an item priced $83 saves $12.45, so you pay $70.55.

Adding and taking away 15%

Increasing 83 by 15% gives 95.45 and decreasing it by 15% gives 70.55. These do not cancel out: raising 83 by 15% and then lowering the result by 15% ends at 81.1325, because the second 15% is taken of a bigger number.
