How to work it out

  1. Turn the percentage into a decimal: 33 ÷ 100 = 0.33
  2. Multiply: 0.33 × 31 = 10.23
  3. Check: Work backwards: 10.23 ÷ 31 × 100 = 33%.

Another method. As a proportion of part to whole: 33/100 = part/31, so part = 33 × 31 ÷ 100 = 10.23. Both methods always give the same answer.

In a spreadsheet: =33%*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

10.23 is the 33% share of 31. The remaining 67% is 20.77, and the two parts add back up to 31.

Discounts: 33% off an item priced $31 saves $10.23, so you pay $20.77.

Adding and taking away 33%

Increasing 31 by 33% gives 41.23 and decreasing it by 33% gives 20.77. These do not cancel out: raising 31 by 33% and then lowering the result by 33% ends at 27.6241, because the second 33% is taken of a bigger number.
