How to work it out

  1. Turn the percentage into a decimal: 18 ÷ 100 = 0.18
  2. Multiply: 0.18 × 84 = 15.12
  3. Check: Work backwards: 15.12 ÷ 84 × 100 = 18%.

Another method. As a proportion of part to whole: 18/100 = part/84, so part = 18 × 84 ÷ 100 = 15.12. Both methods always give the same answer.

In a spreadsheet: =18%*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

15.12 is the 18% share of 84. The remaining 82% is 68.88, and the two parts add back up to 84.

Discounts: 18% off an item priced $84 saves $15.12, so you pay $68.88.

Adding and taking away 18%

Increasing 84 by 18% gives 99.12 and decreasing it by 18% gives 68.88. These do not cancel out: raising 84 by 18% and then lowering the result by 18% ends at 81.2784, because the second 18% is taken of a bigger number.
