How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 79 = 24.49
  3. Check: Work backwards: 24.49 ÷ 79 × 100 = 31%.

Another method. As a proportion of part to whole: 31/100 = part/79, so part = 31 × 79 ÷ 100 = 24.49. Both methods always give the same answer.

In a spreadsheet: =31%*79. 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

24.49 is the 31% share of 79. The remaining 69% is 54.51, and the two parts add back up to 79.

Discounts: 31% off an item priced $79 saves $24.49, so you pay $54.51.

Adding and taking away 31%

Increasing 79 by 31% gives 103.49 and decreasing it by 31% gives 54.51. These do not cancel out: raising 79 by 31% and then lowering the result by 31% ends at 71.4081, because the second 31% is taken of a bigger number.
