How to work it out
- Turn the percentage into a decimal: 42 ÷ 100 = 0.42
- Multiply: 0.42 × 18 = 7.56
- Check: Work backwards: 7.56 ÷ 18 × 100 = 42%.
Another method. As a proportion of part to whole: 42/100 = part/18, so part = 42 × 18 ÷ 100 = 7.56. Both methods always give the same answer.
In a spreadsheet: =42%*18. 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 42%
Increasing 18 by 42% gives 25.56 and decreasing it by 42% gives 10.44. These do not cancel out: raising 18 by 42% and then lowering the result by 42% ends at 14.8248, because the second 42% is taken of a bigger number.
