How to work it out

  1. Turn the percentage into a decimal: 61 ÷ 100 = 0.61
  2. Multiply: 0.61 × 31 = 18.91
  3. Check: Work backwards: 18.91 ÷ 31 × 100 = 61%.

Another method. As a proportion of part to whole: 61/100 = part/31, so part = 61 × 31 ÷ 100 = 18.91. Both methods always give the same answer.

In a spreadsheet: =61%*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

18.91 is the 61% share of 31. The remaining 39% is 12.09, and the two parts add back up to 31.

Discounts: 61% off an item priced $31 saves $18.91, so you pay $12.09.

Adding and taking away 61%

Increasing 31 by 61% gives 49.91 and decreasing it by 61% gives 12.09. These do not cancel out: raising 31 by 61% and then lowering the result by 61% ends at 19.4649, because the second 61% is taken of a bigger number.
