How to work it out

  1. Turn the percentage into a decimal: 77 ÷ 100 = 0.77
  2. Multiply: 0.77 × 31 = 23.87
  3. Check: Work backwards: 23.87 ÷ 31 × 100 = 77%.

Another method. As a proportion of part to whole: 77/100 = part/31, so part = 77 × 31 ÷ 100 = 23.87. Both methods always give the same answer.

In a spreadsheet: =77%*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

23.87 is the 77% share of 31. The remaining 23% is 7.13, and the two parts add back up to 31.

Discounts: 77% off an item priced $31 saves $23.87, so you pay $7.13.

Adding and taking away 77%

Increasing 31 by 77% gives 54.87 and decreasing it by 77% gives 7.13. These do not cancel out: raising 31 by 77% and then lowering the result by 77% ends at 12.6201, because the second 77% is taken of a bigger number.
