How to work it out
- Turn the percentage into a decimal: 70 ÷ 100 = 0.7
- Multiply: 0.7 × 100 = 70
- Check: Work backwards: 70 ÷ 100 × 100 = 70%.
Another method. As a proportion of part to whole: 70/100 = part/100, so part = 70 × 100 ÷ 100 = 70. Both methods always give the same answer.
In a spreadsheet: =70%*100. 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
70 is the 70% share of 100. The remaining 30% is 30, and the two parts add back up to 100.
Discounts: 70% off an item priced $100 saves $70, so you pay $30.
Adding and taking away 70%
Increasing 100 by 70% gives 170 and decreasing it by 70% gives 30. These do not cancel out: raising 100 by 70% and then lowering the result by 70% ends at 51, because the second 70% is taken of a bigger number.
