How to work it out
- Turn the percentage into a decimal: 81 ÷ 100 = 0.81
- Multiply: 0.81 × 38 = 30.78
- Check: Work backwards: 30.78 ÷ 38 × 100 = 81%.
Another method. As a proportion of part to whole: 81/100 = part/38, so part = 81 × 38 ÷ 100 = 30.78. Both methods always give the same answer.
In a spreadsheet: =81%*38. 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 81%
Increasing 38 by 81% gives 68.78 and decreasing it by 81% gives 7.22. These do not cancel out: raising 38 by 81% and then lowering the result by 81% ends at 13.0682, because the second 81% is taken of a bigger number.
