How to work it out
- Turn the percentage into a decimal: 77 ÷ 100 = 0.77
- Multiply: 0.77 × 18 = 13.86
- Check: Work backwards: 13.86 ÷ 18 × 100 = 77%.
Another method. As a proportion of part to whole: 77/100 = part/18, so part = 77 × 18 ÷ 100 = 13.86. Both methods always give the same answer.
In a spreadsheet: =77%*18. 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
13.86 is the 77% share of 18. The remaining 23% is 4.14, and the two parts add back up to 18.

Adding and taking away 77%
Increasing 18 by 77% gives 31.86 and decreasing it by 77% gives 4.14. These do not cancel out: raising 18 by 77% and then lowering the result by 77% ends at 7.3278, because the second 77% is taken of a bigger number.
