How to work it out
- Turn the percentage into a decimal: 84 ÷ 100 = 0.84
- Multiply: 0.84 × 45 = 37.8
- Check: Work backwards: 37.8 ÷ 45 × 100 = 84%.
Another method. As a proportion of part to whole: 84/100 = part/45, so part = 84 × 45 ÷ 100 = 37.8. Both methods always give the same answer.
In a spreadsheet: =84%*45. 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
37.8 is the 84% share of 45. The remaining 16% is 7.2, and the two parts add back up to 45.

Adding and taking away 84%
Increasing 45 by 84% gives 82.8 and decreasing it by 84% gives 7.2. These do not cancel out: raising 45 by 84% and then lowering the result by 84% ends at 13.248, because the second 84% is taken of a bigger number.
