How to work it out

  1. Turn the percentage into a decimal: 20 ÷ 100 = 0.2
  2. Multiply: 0.2 × 72 = 14.4
  3. Check: Work backwards: 14.4 ÷ 72 × 100 = 20%.

Another method. As a proportion of part to whole: 20/100 = part/72, so part = 20 × 72 ÷ 100 = 14.4. Both methods always give the same answer.

In a spreadsheet: =20%*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

14.4 is the 20% share of 72. The remaining 80% is 57.6, and the two parts add back up to 72.

Discounts: 20% off an item priced $72 saves $14.4, so you pay $57.6.

Adding and taking away 20%

Increasing 72 by 20% gives 86.4 and decreasing it by 20% gives 57.6. These do not cancel out: raising 72 by 20% and then lowering the result by 20% ends at 69.12, because the second 20% is taken of a bigger number.
