How to work it out

  1. Turn the percentage into a decimal: 15 ÷ 100 = 0.15
  2. Multiply: 0.15 × 84 = 12.6
  3. Check: Work backwards: 12.6 ÷ 84 × 100 = 15%.

Another method. As a proportion of part to whole: 15/100 = part/84, so part = 15 × 84 ÷ 100 = 12.6. Both methods always give the same answer.

In a spreadsheet: =15%*84. 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

12.6 is the 15% share of 84. The remaining 85% is 71.4, and the two parts add back up to 84.

Discounts: 15% off an item priced $84 saves $12.6, so you pay $71.4.

Adding and taking away 15%

Increasing 84 by 15% gives 96.6 and decreasing it by 15% gives 71.4. These do not cancel out: raising 84 by 15% and then lowering the result by 15% ends at 82.11, because the second 15% is taken of a bigger number.
