How to work it out

  1. Turn the percentage into a decimal: 58 ÷ 100 = 0.58
  2. Multiply: 0.58 × 31 = 17.98
  3. Check: Work backwards: 17.98 ÷ 31 × 100 = 58%.

Another method. As a proportion of part to whole: 58/100 = part/31, so part = 58 × 31 ÷ 100 = 17.98. Both methods always give the same answer.

In a spreadsheet: =58%*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

17.98 is the 58% share of 31. The remaining 42% is 13.02, and the two parts add back up to 31.

Discounts: 58% off an item priced $31 saves $17.98, so you pay $13.02.

Adding and taking away 58%

Increasing 31 by 58% gives 48.98 and decreasing it by 58% gives 13.02. These do not cancel out: raising 31 by 58% and then lowering the result by 58% ends at 20.5716, because the second 58% is taken of a bigger number.
