How to work it out

  1. Turn the percentage into a decimal: 40 ÷ 100 = 0.4
  2. Multiply: 0.4 × 58 = 23.2
  3. Check: Work backwards: 23.2 ÷ 58 × 100 = 40%.

Another method. As a proportion of part to whole: 40/100 = part/58, so part = 40 × 58 ÷ 100 = 23.2. Both methods always give the same answer.

In a spreadsheet: =40%*58. 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

23.2 is the 40% share of 58. The remaining 60% is 34.8, and the two parts add back up to 58.

Discounts: 40% off an item priced $58 saves $23.2, so you pay $34.8.

Adding and taking away 40%

Increasing 58 by 40% gives 81.2 and decreasing it by 40% gives 34.8. These do not cancel out: raising 58 by 40% and then lowering the result by 40% ends at 48.72, because the second 40% is taken of a bigger number.
