How to work it out

  1. Turn the percentage into a decimal: 72 ÷ 100 = 0.72
  2. Multiply: 0.72 × 42 = 30.24
  3. Check: Work backwards: 30.24 ÷ 42 × 100 = 72%.

Another method. As a proportion of part to whole: 72/100 = part/42, so part = 72 × 42 ÷ 100 = 30.24. Both methods always give the same answer.

In a spreadsheet: =72%*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

30.24 is the 72% share of 42. The remaining 28% is 11.76, and the two parts add back up to 42.

Discounts: 72% off an item priced $42 saves $30.24, so you pay $11.76.

Adding and taking away 72%

Increasing 42 by 72% gives 72.24 and decreasing it by 72% gives 11.76. These do not cancel out: raising 42 by 72% and then lowering the result by 72% ends at 20.2272, because the second 72% is taken of a bigger number.
