How to work it out

  1. Turn the percentage into a decimal: 40 ÷ 100 = 0.4
  2. Multiply: 0.4 × 23 = 9.2
  3. Check: Work backwards: 9.2 ÷ 23 × 100 = 40%.

Another method. As a proportion of part to whole: 40/100 = part/23, so part = 40 × 23 ÷ 100 = 9.2. Both methods always give the same answer.

In a spreadsheet: =40%*23. 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

9.2 is the 40% share of 23. The remaining 60% is 13.8, and the two parts add back up to 23.

Discounts: 40% off an item priced $23 saves $9.2, so you pay $13.8.

Adding and taking away 40%

Increasing 23 by 40% gives 32.2 and decreasing it by 40% gives 13.8. These do not cancel out: raising 23 by 40% and then lowering the result by 40% ends at 19.32, because the second 40% is taken of a bigger number.
