How to work it out
- Turn the percentage into a decimal: 30 ÷ 100 = 0.3
- Multiply: 0.3 × 55 = 16.5
- Check: Work backwards: 16.5 ÷ 55 × 100 = 30%.
Another method. As a proportion of part to whole: 30/100 = part/55, so part = 30 × 55 ÷ 100 = 16.5. Both methods always give the same answer.
In a spreadsheet: =30%*55. 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 30% share of 55. The remaining 70% is 38.5, and the two parts add back up to 55.
Discounts: 30% off an item priced $55 saves $16.5, so you pay $38.5.
Adding and taking away 30%
Increasing 55 by 30% gives 71.5 and decreasing it by 30% gives 38.5. These do not cancel out: raising 55 by 30% and then lowering the result by 30% ends at 50.05, because the second 30% is taken of a bigger number.
