How to work it out

  1. Turn the percentage into a decimal: 43 ÷ 100 = 0.43
  2. Multiply: 0.43 × 31 = 13.33
  3. Check: Work backwards: 13.33 ÷ 31 × 100 = 43%.

Another method. As a proportion of part to whole: 43/100 = part/31, so part = 43 × 31 ÷ 100 = 13.33. Both methods always give the same answer.

In a spreadsheet: =43%*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

13.33 is the 43% share of 31. The remaining 57% is 17.67, and the two parts add back up to 31.

Discounts: 43% off an item priced $31 saves $13.33, so you pay $17.67.

Adding and taking away 43%

Increasing 31 by 43% gives 44.33 and decreasing it by 43% gives 17.67. These do not cancel out: raising 31 by 43% and then lowering the result by 43% ends at 25.2681, because the second 43% is taken of a bigger number.
