How to work it out
- Turn the percentage into a decimal: 42 ÷ 100 = 0.42
- Multiply: 0.42 × 57 = 23.94
- Check: Work backwards: 23.94 ÷ 57 × 100 = 42%.
Another method. As a proportion of part to whole: 42/100 = part/57, so part = 42 × 57 ÷ 100 = 23.94. Both methods always give the same answer.
In a spreadsheet: =42%*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
23.94 is the 42% share of 57. The remaining 58% is 33.06, and the two parts add back up to 57.

Adding and taking away 42%
Increasing 57 by 42% gives 80.94 and decreasing it by 42% gives 33.06. These do not cancel out: raising 57 by 42% and then lowering the result by 42% ends at 46.9452, because the second 42% is taken of a bigger number.
