How to work it out
- Turn the percentage into a decimal: 18 ÷ 100 = 0.18
- Multiply: 0.18 × 51 = 9.18
- Check: Work backwards: 9.18 ÷ 51 × 100 = 18%.
Another method. As a proportion of part to whole: 18/100 = part/51, so part = 18 × 51 ÷ 100 = 9.18. Both methods always give the same answer.
In a spreadsheet: =18%*51. 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

Adding and taking away 18%
Increasing 51 by 18% gives 60.18 and decreasing it by 18% gives 41.82. These do not cancel out: raising 51 by 18% and then lowering the result by 18% ends at 49.3476, because the second 18% is taken of a bigger number.
