How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 29 = 8.99
  3. Check: Work backwards: 8.99 ÷ 29 × 100 = 31%.

Another method. As a proportion of part to whole: 31/100 = part/29, so part = 31 × 29 ÷ 100 = 8.99. Both methods always give the same answer.

In a spreadsheet: =31%*29. 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

8.99 is the 31% share of 29. The remaining 69% is 20.01, and the two parts add back up to 29.

Discounts: 31% off an item priced $29 saves $8.99, so you pay $20.01.

Adding and taking away 31%

Increasing 29 by 31% gives 37.99 and decreasing it by 31% gives 20.01. These do not cancel out: raising 29 by 31% and then lowering the result by 31% ends at 26.2131, because the second 31% is taken of a bigger number.
