How to work it out
- Turn the percentage into a decimal: 21 ÷ 100 = 0.21
- Multiply: 0.21 × 27 = 5.67
- Check: Work backwards: 5.67 ÷ 27 × 100 = 21%.
Another method. As a proportion of part to whole: 21/100 = part/27, so part = 21 × 27 ÷ 100 = 5.67. Both methods always give the same answer.
In a spreadsheet: =21%*27. 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

Adding and taking away 21%
Increasing 27 by 21% gives 32.67 and decreasing it by 21% gives 21.33. These do not cancel out: raising 27 by 21% and then lowering the result by 21% ends at 25.8093, because the second 21% is taken of a bigger number.
