How to work it out

  1. Turn the percentage into a decimal: 42 ÷ 100 = 0.42
  2. Multiply: 0.42 × 72 = 30.24
  3. Check: Work backwards: 30.24 ÷ 72 × 100 = 42%.

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

In a spreadsheet: =42%*72. 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 42% share of 72. The remaining 58% is 41.76, and the two parts add back up to 72.

Discounts: 42% off an item priced $72 saves $30.24, so you pay $41.76.

Adding and taking away 42%

Increasing 72 by 42% gives 102.24 and decreasing it by 42% gives 41.76. These do not cancel out: raising 72 by 42% and then lowering the result by 42% ends at 59.2992, because the second 42% is taken of a bigger number.
