How to work it out
- Turn the percentage into a decimal: 91 ÷ 100 = 0.91
- Multiply: 0.91 × 42 = 38.22
- Check: Work backwards: 38.22 ÷ 42 × 100 = 91%.
Another method. As a proportion of part to whole: 91/100 = part/42, so part = 91 × 42 ÷ 100 = 38.22. Both methods always give the same answer.
In a spreadsheet: =91%*42. 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 91%
Increasing 42 by 91% gives 80.22 and decreasing it by 91% gives 3.78. These do not cancel out: raising 42 by 91% and then lowering the result by 91% ends at 7.2198, because the second 91% is taken of a bigger number.
