How to work it out
- Turn the percentage into a decimal: 73 ÷ 100 = 0.73
- Multiply: 0.73 × 30 = 21.9
- Check: Work backwards: 21.9 ÷ 30 × 100 = 73%.
Another method. As a proportion of part to whole: 73/100 = part/30, so part = 73 × 30 ÷ 100 = 21.9. Both methods always give the same answer.
In a spreadsheet: =73%*30. 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
21.9 is the 73% share of 30. The remaining 27% is 8.1, and the two parts add back up to 30.
Discounts: 73% off an item priced $30 saves $21.9, so you pay $8.1.
Adding and taking away 73%
Increasing 30 by 73% gives 51.9 and decreasing it by 73% gives 8.1. These do not cancel out: raising 30 by 73% and then lowering the result by 73% ends at 14.013, because the second 73% is taken of a bigger number.
