How to work it out

  1. Turn the percentage into a decimal: 79 ÷ 100 = 0.79
  2. Multiply: 0.79 × 31 = 24.49
  3. Check: Work backwards: 24.49 ÷ 31 × 100 = 79%.

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

In a spreadsheet: =79%*31. 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 79% share of 31. The remaining 21% is 6.51, and the two parts add back up to 31.

Discounts: 79% off an item priced $31 saves $24.49, so you pay $6.51.

Adding and taking away 79%

Increasing 31 by 79% gives 55.49 and decreasing it by 79% gives 6.51. These do not cancel out: raising 31 by 79% and then lowering the result by 79% ends at 11.6529, because the second 79% is taken of a bigger number.
