How to work it out

  1. Turn the percentage into a decimal: 81 ÷ 100 = 0.81
  2. Multiply: 0.81 × 82 = 66.42
  3. Check: Work backwards: 66.42 ÷ 82 × 100 = 81%.

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

In a spreadsheet: =81%*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

66.42 is the 81% share of 82. The remaining 19% is 15.58, and the two parts add back up to 82.

Discounts: 81% off an item priced $82 saves $66.42, so you pay $15.58.

Adding and taking away 81%

Increasing 82 by 81% gives 148.42 and decreasing it by 81% gives 15.58. These do not cancel out: raising 82 by 81% and then lowering the result by 81% ends at 28.1998, because the second 81% is taken of a bigger number.
