How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 8 = 2.48
  3. Check: Work backwards: 2.48 ÷ 8 × 100 = 31%.

Another method. As a proportion of part to whole: 31/100 = part/8, so part = 31 × 8 ÷ 100 = 2.48. Both methods always give the same answer.

In a spreadsheet: =31%*8. 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

2.48 is the 31% share of 8. The remaining 69% is 5.52, and the two parts add back up to 8.

Discounts: 31% off an item priced $8 saves $2.48, so you pay $5.52.

Adding and taking away 31%

Increasing 8 by 31% gives 10.48 and decreasing it by 31% gives 5.52. These do not cancel out: raising 8 by 31% and then lowering the result by 31% ends at 7.2312, because the second 31% is taken of a bigger number.
