How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 3 = 0.93
  3. Check: Work backwards: 0.93 ÷ 3 × 100 = 31%.

Another method. As a proportion of part to whole: 31/100 = part/3, so part = 31 × 3 ÷ 100 = 0.93. Both methods always give the same answer.

In a spreadsheet: =31%*3. 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

0.93 is the 31% share of 3. The remaining 69% is 2.07, and the two parts add back up to 3.

Discounts: 31% off an item priced $3 saves $0.93, so you pay $2.07.

Adding and taking away 31%

Increasing 3 by 31% gives 3.93 and decreasing it by 31% gives 2.07. These do not cancel out: raising 3 by 31% and then lowering the result by 31% ends at 2.7117, because the second 31% is taken of a bigger number.
