How to work it out
- Turn the percentage into a decimal: 64 ÷ 100 = 0.64
- Multiply: 0.64 × 45 = 28.8
- Check: Work backwards: 28.8 ÷ 45 × 100 = 64%.
Another method. As a proportion of part to whole: 64/100 = part/45, so part = 64 × 45 ÷ 100 = 28.8. Both methods always give the same answer.
In a spreadsheet: =64%*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
28.8 is the 64% share of 45. The remaining 36% is 16.2, and the two parts add back up to 45.

Adding and taking away 64%
Increasing 45 by 64% gives 73.8 and decreasing it by 64% gives 16.2. These do not cancel out: raising 45 by 64% and then lowering the result by 64% ends at 26.568, because the second 64% is taken of a bigger number.
