How to work it out
- Turn the percentage into a decimal: 45 ÷ 100 = 0.45
- Multiply: 0.45 × 91 = 40.95
- Check: Work backwards: 40.95 ÷ 91 × 100 = 45%.
Another method. As a proportion of part to whole: 45/100 = part/91, so part = 45 × 91 ÷ 100 = 40.95. Both methods always give the same answer.
In a spreadsheet: =45%*91. 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

Adding and taking away 45%
Increasing 91 by 45% gives 131.95 and decreasing it by 45% gives 50.05. These do not cancel out: raising 91 by 45% and then lowering the result by 45% ends at 72.5725, because the second 45% is taken of a bigger number.
