How to work it out
- Turn the percentage into a decimal: 3 ÷ 100 = 0.03
- Multiply: 0.03 × 42 = 1.26
- Check: Work backwards: 1.26 ÷ 42 × 100 = 3%.
Another method. As a proportion of part to whole: 3/100 = part/42, so part = 3 × 42 ÷ 100 = 1.26. Both methods always give the same answer.
In a spreadsheet: =3%*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
1.26 is the 3% share of 42. The remaining 97% is 40.74, and the two parts add back up to 42.

Adding and taking away 3%
Increasing 42 by 3% gives 43.26 and decreasing it by 3% gives 40.74. These do not cancel out: raising 42 by 3% and then lowering the result by 3% ends at 41.9622, because the second 3% is taken of a bigger number.
