How to work it out
- Turn the percentage into a decimal: 70 ÷ 100 = 0.7
- Multiply: 0.7 × 3 = 2.1
- Check: Work backwards: 2.1 ÷ 3 × 100 = 70%.
Another method. As a proportion of part to whole: 70/100 = part/3, so part = 70 × 3 ÷ 100 = 2.1. Both methods always give the same answer.
In a spreadsheet: =70%*3. 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
2.1 is the 70% share of 3. The remaining 30% is 0.9, and the two parts add back up to 3.
Discounts: 70% off an item priced $3 saves $2.1, so you pay $0.9.
Adding and taking away 70%
Increasing 3 by 70% gives 5.1 and decreasing it by 70% gives 0.9. These do not cancel out: raising 3 by 70% and then lowering the result by 70% ends at 1.53, because the second 70% is taken of a bigger number.
