How to work it out
- Turn the percentage into a decimal: 45 ÷ 100 = 0.45
- Multiply: 0.45 × 70 = 31.5
- Check: Work backwards: 31.5 ÷ 70 × 100 = 45%.
Another method. As a proportion of part to whole: 45/100 = part/70, so part = 45 × 70 ÷ 100 = 31.5. Both methods always give the same answer.
In a spreadsheet: =45%*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
31.5 is the 45% share of 70. The remaining 55% is 38.5, and the two parts add back up to 70.
Discounts: 45% off an item priced $70 saves $31.5, so you pay $38.5.
Adding and taking away 45%
Increasing 70 by 45% gives 101.5 and decreasing it by 45% gives 38.5. These do not cancel out: raising 70 by 45% and then lowering the result by 45% ends at 55.825, because the second 45% is taken of a bigger number.
