How to work it out
- Turn the percentage into a decimal: 12 ÷ 100 = 0.12
- Multiply: 0.12 × 42 = 5.04
- Check: Work backwards: 5.04 ÷ 42 × 100 = 12%.
Another method. As a proportion of part to whole: 12/100 = part/42, so part = 12 × 42 ÷ 100 = 5.04. Both methods always give the same answer.
In a spreadsheet: =12%*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

Adding and taking away 12%
Increasing 42 by 12% gives 47.04 and decreasing it by 12% gives 36.96. These do not cancel out: raising 42 by 12% and then lowering the result by 12% ends at 41.3952, because the second 12% is taken of a bigger number.
