How to work it out
- Turn the percentage into a decimal: 42 ÷ 100 = 0.42
- Multiply: 0.42 × 8 = 3.36
- Check: Work backwards: 3.36 ÷ 8 × 100 = 42%.
Another method. As a proportion of part to whole: 42/100 = part/8, so part = 42 × 8 ÷ 100 = 3.36. Both methods always give the same answer.
In a spreadsheet: =42%*8. 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
3.36 is the 42% share of 8. The remaining 58% is 4.64, and the two parts add back up to 8.

Adding and taking away 42%
Increasing 8 by 42% gives 11.36 and decreasing it by 42% gives 4.64. These do not cancel out: raising 8 by 42% and then lowering the result by 42% ends at 6.5888, because the second 42% is taken of a bigger number.
