How to work it out

  1. Turn the percentage into a decimal: 84 ÷ 100 = 0.84
  2. Multiply: 0.84 × 81 = 68.04
  3. Check: Work backwards: 68.04 ÷ 81 × 100 = 84%.

Another method. As a proportion of part to whole: 84/100 = part/81, so part = 84 × 81 ÷ 100 = 68.04. Both methods always give the same answer.

In a spreadsheet: =84%*81. 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

68.04 is the 84% share of 81. The remaining 16% is 12.96, and the two parts add back up to 81.

Discounts: 84% off an item priced $81 saves $68.04, so you pay $12.96.

Adding and taking away 84%

Increasing 81 by 84% gives 149.04 and decreasing it by 84% gives 12.96. These do not cancel out: raising 81 by 84% and then lowering the result by 84% ends at 23.8464, because the second 84% is taken of a bigger number.
