How to work it out

  1. Turn the percentage into a decimal: 80 ÷ 100 = 0.8
  2. Multiply: 0.8 × 36 = 28.8
  3. Check: Work backwards: 28.8 ÷ 36 × 100 = 80%.

Another method. As a proportion of part to whole: 80/100 = part/36, so part = 80 × 36 ÷ 100 = 28.8. Both methods always give the same answer.

In a spreadsheet: =80%*36. 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

28.8 is the 80% share of 36. The remaining 20% is 7.2, and the two parts add back up to 36.

Discounts: 80% off an item priced $36 saves $28.8, so you pay $7.2.

Adding and taking away 80%

Increasing 36 by 80% gives 64.8 and decreasing it by 80% gives 7.2. These do not cancel out: raising 36 by 80% and then lowering the result by 80% ends at 12.96, because the second 80% is taken of a bigger number.
