How to work it out
- Turn the percentage into a decimal: 55 ÷ 100 = 0.55
- Multiply: 0.55 × 57 = 31.35
- Check: Work backwards: 31.35 ÷ 57 × 100 = 55%.
Another method. As a proportion of part to whole: 55/100 = part/57, so part = 55 × 57 ÷ 100 = 31.35. Both methods always give the same answer.
In a spreadsheet: =55%*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
31.35 is the 55% share of 57. The remaining 45% is 25.65, and the two parts add back up to 57.

Adding and taking away 55%
Increasing 57 by 55% gives 88.35 and decreasing it by 55% gives 25.65. These do not cancel out: raising 57 by 55% and then lowering the result by 55% ends at 39.7575, because the second 55% is taken of a bigger number.
