How to work it out

  1. Turn the percentage into a decimal: 15 ÷ 100 = 0.15
  2. Multiply: 0.15 × 82 = 12.3
  3. Check: Work backwards: 12.3 ÷ 82 × 100 = 15%.

Another method. As a proportion of part to whole: 15/100 = part/82, so part = 15 × 82 ÷ 100 = 12.3. Both methods always give the same answer.

In a spreadsheet: =15%*82. 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

12.3 is the 15% share of 82. The remaining 85% is 69.7, and the two parts add back up to 82.

Discounts: 15% off an item priced $82 saves $12.3, so you pay $69.7.

Adding and taking away 15%

Increasing 82 by 15% gives 94.3 and decreasing it by 15% gives 69.7. These do not cancel out: raising 82 by 15% and then lowering the result by 15% ends at 80.155, because the second 15% is taken of a bigger number.
