How to work it out
- Turn the percentage into a decimal: 39 ÷ 100 = 0.39
- Multiply: 0.39 × 80 = 31.2
- Check: Work backwards: 31.2 ÷ 80 × 100 = 39%.
Another method. As a proportion of part to whole: 39/100 = part/80, so part = 39 × 80 ÷ 100 = 31.2. Both methods always give the same answer.
In a spreadsheet: =39%*80. 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
31.2 is the 39% share of 80. The remaining 61% is 48.8, and the two parts add back up to 80.

Adding and taking away 39%
Increasing 80 by 39% gives 111.2 and decreasing it by 39% gives 48.8. These do not cancel out: raising 80 by 39% and then lowering the result by 39% ends at 67.832, because the second 39% is taken of a bigger number.
