How to work it out

  1. Turn the percentage into a decimal: 24 ÷ 100 = 0.24
  2. Multiply: 0.24 × 42 = 10.08
  3. Check: Work backwards: 10.08 ÷ 42 × 100 = 24%.

Another method. As a proportion of part to whole: 24/100 = part/42, so part = 24 × 42 ÷ 100 = 10.08. Both methods always give the same answer.

In a spreadsheet: =24%*42. 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

10.08 is the 24% share of 42. The remaining 76% is 31.92, and the two parts add back up to 42.

Discounts: 24% off an item priced $42 saves $10.08, so you pay $31.92.

Adding and taking away 24%

Increasing 42 by 24% gives 52.08 and decreasing it by 24% gives 31.92. These do not cancel out: raising 42 by 24% and then lowering the result by 24% ends at 39.5808, because the second 24% is taken of a bigger number.
