How to work it out
- Turn the percentage into a decimal: 42 ÷ 100 = 0.42
- Multiply: 0.42 × 49 = 20.58
- Check: Work backwards: 20.58 ÷ 49 × 100 = 42%.
Another method. As a proportion of part to whole: 42/100 = part/49, so part = 42 × 49 ÷ 100 = 20.58. Both methods always give the same answer.
In a spreadsheet: =42%*49. 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
20.58 is the 42% share of 49. The remaining 58% is 28.42, and the two parts add back up to 49.

Adding and taking away 42%
Increasing 49 by 42% gives 69.58 and decreasing it by 42% gives 28.42. These do not cancel out: raising 49 by 42% and then lowering the result by 42% ends at 40.3564, because the second 42% is taken of a bigger number.
