How to work it out

  1. Turn the percentage into a decimal: 24 ÷ 100 = 0.24
  2. Multiply: 0.24 × 40 = 9.6
  3. Check: Work backwards: 9.6 ÷ 40 × 100 = 24%.

Another method. As a proportion of part to whole: 24/100 = part/40, so part = 24 × 40 ÷ 100 = 9.6. Both methods always give the same answer.

In a spreadsheet: =24%*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

9.6 is the 24% share of 40. The remaining 76% is 30.4, and the two parts add back up to 40.

Discounts: 24% off an item priced $40 saves $9.6, so you pay $30.4.

Adding and taking away 24%

Increasing 40 by 24% gives 49.6 and decreasing it by 24% gives 30.4. These do not cancel out: raising 40 by 24% and then lowering the result by 24% ends at 37.696, because the second 24% is taken of a bigger number.
