How to work it out
- Turn the percentage into a decimal: 90 ÷ 100 = 0.9
- Multiply: 0.9 × 70 = 63
- Check: Work backwards: 63 ÷ 70 × 100 = 90%.
Another method. As a proportion of part to whole: 90/100 = part/70, so part = 90 × 70 ÷ 100 = 63. Both methods always give the same answer.
In a spreadsheet: =90%*70. 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
63 is the 90% share of 70. The remaining 10% is 7, and the two parts add back up to 70.
Discounts: 90% off an item priced $70 saves $63, so you pay $7.
Adding and taking away 90%
Increasing 70 by 90% gives 133 and decreasing it by 90% gives 7. These do not cancel out: raising 70 by 90% and then lowering the result by 90% ends at 13.3, because the second 90% is taken of a bigger number.
