How to work it out
- Turn the percentage into a decimal: 91 ÷ 100 = 0.91
- Multiply: 0.91 × 57 = 51.87
- Check: Work backwards: 51.87 ÷ 57 × 100 = 91%.
Another method. As a proportion of part to whole: 91/100 = part/57, so part = 91 × 57 ÷ 100 = 51.87. Both methods always give the same answer.
In a spreadsheet: =91%*57. 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 57 by 91% gives 108.87 and decreasing it by 91% gives 5.13. These do not cancel out: raising 57 by 91% and then lowering the result by 91% ends at 9.7983, because the second 91% is taken of a bigger number.
