How to work it out
- Turn the percentage into a decimal: 70 ÷ 100 = 0.7
- Multiply: 0.7 × 15 = 10.5
- Check: Work backwards: 10.5 ÷ 15 × 100 = 70%.
Another method. As a proportion of part to whole: 70/100 = part/15, so part = 70 × 15 ÷ 100 = 10.5. Both methods always give the same answer.
In a spreadsheet: =70%*15. 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
10.5 is the 70% share of 15. The remaining 30% is 4.5, and the two parts add back up to 15.
Discounts: 70% off an item priced $15 saves $10.5, so you pay $4.5.
Adding and taking away 70%
Increasing 15 by 70% gives 25.5 and decreasing it by 70% gives 4.5. These do not cancel out: raising 15 by 70% and then lowering the result by 70% ends at 7.65, because the second 70% is taken of a bigger number.
