How to work it out

  1. Turn the percentage into a decimal: 73 ÷ 100 = 0.73
  2. Multiply: 0.73 × 40 = 29.2
  3. Check: Work backwards: 29.2 ÷ 40 × 100 = 73%.

Another method. As a proportion of part to whole: 73/100 = part/40, so part = 73 × 40 ÷ 100 = 29.2. Both methods always give the same answer.

In a spreadsheet: =73%*40. 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

29.2 is the 73% share of 40. The remaining 27% is 10.8, and the two parts add back up to 40.

Discounts: 73% off an item priced $40 saves $29.2, so you pay $10.8.

Adding and taking away 73%

Increasing 40 by 73% gives 69.2 and decreasing it by 73% gives 10.8. These do not cancel out: raising 40 by 73% and then lowering the result by 73% ends at 18.684, because the second 73% is taken of a bigger number.
