How to work it out

  1. Turn the percentage into a decimal: 82 ÷ 100 = 0.82
  2. Multiply: 0.82 × 81 = 66.42
  3. Check: Work backwards: 66.42 ÷ 81 × 100 = 82%.

Another method. As a proportion of part to whole: 82/100 = part/81, so part = 82 × 81 ÷ 100 = 66.42. Both methods always give the same answer.

In a spreadsheet: =82%*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

66.42 is the 82% share of 81. The remaining 18% is 14.58, and the two parts add back up to 81.

Discounts: 82% off an item priced $81 saves $66.42, so you pay $14.58.

Adding and taking away 82%

Increasing 81 by 82% gives 147.42 and decreasing it by 82% gives 14.58. These do not cancel out: raising 81 by 82% and then lowering the result by 82% ends at 26.5356, because the second 82% is taken of a bigger number.
