How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 27 = 8.37
  3. Check: Work backwards: 8.37 ÷ 27 × 100 = 31%.

Another method. As a proportion of part to whole: 31/100 = part/27, so part = 31 × 27 ÷ 100 = 8.37. Both methods always give the same answer.

In a spreadsheet: =31%*27. 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

8.37 is the 31% share of 27. The remaining 69% is 18.63, and the two parts add back up to 27.

Discounts: 31% off an item priced $27 saves $8.37, so you pay $18.63.

Adding and taking away 31%

Increasing 27 by 31% gives 35.37 and decreasing it by 31% gives 18.63. These do not cancel out: raising 27 by 31% and then lowering the result by 31% ends at 24.4053, because the second 31% is taken of a bigger number.
