How to work it out

  1. Turn the percentage into a decimal: 63 ÷ 100 = 0.63
  2. Multiply: 0.63 × 31 = 19.53
  3. Check: Work backwards: 19.53 ÷ 31 × 100 = 63%.

Another method. As a proportion of part to whole: 63/100 = part/31, so part = 63 × 31 ÷ 100 = 19.53. Both methods always give the same answer.

In a spreadsheet: =63%*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

19.53 is the 63% share of 31. The remaining 37% is 11.47, and the two parts add back up to 31.

Discounts: 63% off an item priced $31 saves $19.53, so you pay $11.47.

Adding and taking away 63%

Increasing 31 by 63% gives 50.53 and decreasing it by 63% gives 11.47. These do not cancel out: raising 31 by 63% and then lowering the result by 63% ends at 18.6961, because the second 63% is taken of a bigger number.
