How to work it out

  1. Turn the percentage into a decimal: 72 ÷ 100 = 0.72
  2. Multiply: 0.72 × 80 = 57.6
  3. Check: Work backwards: 57.6 ÷ 80 × 100 = 72%.

Another method. As a proportion of part to whole: 72/100 = part/80, so part = 72 × 80 ÷ 100 = 57.6. Both methods always give the same answer.

In a spreadsheet: =72%*80. 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

57.6 is the 72% share of 80. The remaining 28% is 22.4, and the two parts add back up to 80.

Discounts: 72% off an item priced $80 saves $57.6, so you pay $22.4.

Adding and taking away 72%

Increasing 80 by 72% gives 137.6 and decreasing it by 72% gives 22.4. These do not cancel out: raising 80 by 72% and then lowering the result by 72% ends at 38.528, because the second 72% is taken of a bigger number.
