How to work it out

  1. Turn the percentage into a decimal: 27 ÷ 100 = 0.27
  2. Multiply: 0.27 × 20 = 5.4
  3. Check: Work backwards: 5.4 ÷ 20 × 100 = 27%.

Another method. As a proportion of part to whole: 27/100 = part/20, so part = 27 × 20 ÷ 100 = 5.4. Both methods always give the same answer.

In a spreadsheet: =27%*20. 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

5.4 is the 27% share of 20. The remaining 73% is 14.6, and the two parts add back up to 20.

Discounts: 27% off an item priced $20 saves $5.4, so you pay $14.6.

Adding and taking away 27%

Increasing 20 by 27% gives 25.4 and decreasing it by 27% gives 14.6. These do not cancel out: raising 20 by 27% and then lowering the result by 27% ends at 18.542, because the second 27% is taken of a bigger number.
