How to work it out
- Turn the percentage into a decimal: 79 ÷ 100 = 0.79
- Multiply: 0.79 × 42 = 33.18
- Check: Work backwards: 33.18 ÷ 42 × 100 = 79%.
Another method. As a proportion of part to whole: 79/100 = part/42, so part = 79 × 42 ÷ 100 = 33.18. Both methods always give the same answer.
In a spreadsheet: =79%*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.

Adding and taking away 79%
Increasing 42 by 79% gives 75.18 and decreasing it by 79% gives 8.82. These do not cancel out: raising 42 by 79% and then lowering the result by 79% ends at 15.7878, because the second 79% is taken of a bigger number.
