How to work it out
- Turn the percentage into a decimal: 38 ÷ 100 = 0.38
- Multiply: 0.38 × 81 = 30.78
- Check: Work backwards: 30.78 ÷ 81 × 100 = 38%.
Another method. As a proportion of part to whole: 38/100 = part/81, so part = 38 × 81 ÷ 100 = 30.78. Both methods always give the same answer.
In a spreadsheet: =38%*81. 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 38%
Increasing 81 by 38% gives 111.78 and decreasing it by 38% gives 50.22. These do not cancel out: raising 81 by 38% and then lowering the result by 38% ends at 69.3036, because the second 38% is taken of a bigger number.
