How to work it out
- Turn the percentage into a decimal: 66 ÷ 100 = 0.66
- Multiply: 0.66 × 42 = 27.72
- Check: Work backwards: 27.72 ÷ 42 × 100 = 66%.
Another method. As a proportion of part to whole: 66/100 = part/42, so part = 66 × 42 ÷ 100 = 27.72. Both methods always give the same answer.
In a spreadsheet: =66%*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 66%
Increasing 42 by 66% gives 69.72 and decreasing it by 66% gives 14.28. These do not cancel out: raising 42 by 66% and then lowering the result by 66% ends at 23.7048, because the second 66% is taken of a bigger number.
