How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 83 = 25.73
  3. Check: Work backwards: 25.73 ÷ 83 × 100 = 31%.

Another method. As a proportion of part to whole: 31/100 = part/83, so part = 31 × 83 ÷ 100 = 25.73. Both methods always give the same answer.

In a spreadsheet: =31%*83. 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

25.73 is the 31% share of 83. The remaining 69% is 57.27, and the two parts add back up to 83.

Discounts: 31% off an item priced $83 saves $25.73, so you pay $57.27.

Adding and taking away 31%

Increasing 83 by 31% gives 108.73 and decreasing it by 31% gives 57.27. These do not cancel out: raising 83 by 31% and then lowering the result by 31% ends at 75.0237, because the second 31% is taken of a bigger number.
