How to work it out
- Turn the percentage into a decimal: 31 ÷ 100 = 0.31
- Multiply: 0.31 × 31 = 9.61
- Check: Work backwards: 9.61 ÷ 31 × 100 = 31%.
Another method. As a proportion of part to whole: 31/100 = part/31, so part = 31 × 31 ÷ 100 = 9.61. Both methods always give the same answer.
In a spreadsheet: =31%*31. 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
9.61 is the 31% share of 31. The remaining 69% is 21.39, and the two parts add back up to 31.
Discounts: 31% off an item priced $31 saves $9.61, so you pay $21.39.
Adding and taking away 31%
Increasing 31 by 31% gives 40.61 and decreasing it by 31% gives 21.39. These do not cancel out: raising 31 by 31% and then lowering the result by 31% ends at 28.0209, because the second 31% is taken of a bigger number.
