How to work it out
- Turn the percentage into a decimal: 81 ÷ 100 = 0.81
- Multiply: 0.81 × 85 = 68.85
- Check: Work backwards: 68.85 ÷ 85 × 100 = 81%.
Another method. As a proportion of part to whole: 81/100 = part/85, so part = 81 × 85 ÷ 100 = 68.85. Both methods always give the same answer.
In a spreadsheet: =81%*85. 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 85 by 81% gives 153.85 and decreasing it by 81% gives 16.15. These do not cancel out: raising 85 by 81% and then lowering the result by 81% ends at 29.2315, because the second 81% is taken of a bigger number.
