How to work it out
- Turn the percentage into a decimal: 81 ÷ 100 = 0.81
- Multiply: 0.81 × 8 = 6.48
- Check: Work backwards: 6.48 ÷ 8 × 100 = 81%.
Another method. As a proportion of part to whole: 81/100 = part/8, so part = 81 × 8 ÷ 100 = 6.48. Both methods always give the same answer.
In a spreadsheet: =81%*8. 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
6.48 is the 81% share of 8. The remaining 19% is 1.52, and the two parts add back up to 8.
Discounts: 81% off an item priced $8 saves $6.48, so you pay $1.52.
Adding and taking away 81%
Increasing 8 by 81% gives 14.48 and decreasing it by 81% gives 1.52. These do not cancel out: raising 8 by 81% and then lowering the result by 81% ends at 2.7512, because the second 81% is taken of a bigger number.
