How to work it out
- Turn the percentage into a decimal: 31 ÷ 100 = 0.31
- Multiply: 0.31 × 28 = 8.68
- Check: Work backwards: 8.68 ÷ 28 × 100 = 31%.
Another method. As a proportion of part to whole: 31/100 = part/28, so part = 31 × 28 ÷ 100 = 8.68. Both methods always give the same answer.
In a spreadsheet: =31%*28. 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 31%
Increasing 28 by 31% gives 36.68 and decreasing it by 31% gives 19.32. These do not cancel out: raising 28 by 31% and then lowering the result by 31% ends at 25.3092, because the second 31% is taken of a bigger number.
