How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 82 = 25.42
  3. Check: Work backwards: 25.42 ÷ 82 × 100 = 31%.

Another method. As a proportion of part to whole: 31/100 = part/82, so part = 31 × 82 ÷ 100 = 25.42. Both methods always give the same answer.

In a spreadsheet: =31%*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

25.42 is the 31% share of 82. The remaining 69% is 56.58, and the two parts add back up to 82.

Discounts: 31% off an item priced $82 saves $25.42, so you pay $56.58.

Adding and taking away 31%

Increasing 82 by 31% gives 107.42 and decreasing it by 31% gives 56.58. These do not cancel out: raising 82 by 31% and then lowering the result by 31% ends at 74.1198, because the second 31% is taken of a bigger number.
