How to work it out
- Turn the percentage into a decimal: 55 ÷ 100 = 0.55
- Multiply: 0.55 × 30 = 16.5
- Check: Work backwards: 16.5 ÷ 30 × 100 = 55%.
Another method. As a proportion of part to whole: 55/100 = part/30, so part = 55 × 30 ÷ 100 = 16.5. Both methods always give the same answer.
In a spreadsheet: =55%*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
16.5 is the 55% share of 30. The remaining 45% is 13.5, and the two parts add back up to 30.
Discounts: 55% off an item priced $30 saves $16.5, so you pay $13.5.
Adding and taking away 55%
Increasing 30 by 55% gives 46.5 and decreasing it by 55% gives 13.5. These do not cancel out: raising 30 by 55% and then lowering the result by 55% ends at 20.925, because the second 55% is taken of a bigger number.
