How to work it out

  1. Turn the percentage into a decimal: 27 ÷ 100 = 0.27
  2. Multiply: 0.27 × 80 = 21.6
  3. Check: Work backwards: 21.6 ÷ 80 × 100 = 27%.

Another method. As a proportion of part to whole: 27/100 = part/80, so part = 27 × 80 ÷ 100 = 21.6. Both methods always give the same answer.

In a spreadsheet: =27%*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

21.6 is the 27% share of 80. The remaining 73% is 58.4, and the two parts add back up to 80.

Discounts: 27% off an item priced $80 saves $21.6, so you pay $58.4.

Adding and taking away 27%

Increasing 80 by 27% gives 101.6 and decreasing it by 27% gives 58.4. These do not cancel out: raising 80 by 27% and then lowering the result by 27% ends at 74.168, because the second 27% is taken of a bigger number.
