How to work it out
- Turn the percentage into a decimal: 71 ÷ 100 = 0.71
- Multiply: 0.71 × 81 = 57.51
- Check: Work backwards: 57.51 ÷ 81 × 100 = 71%.
Another method. As a proportion of part to whole: 71/100 = part/81, so part = 71 × 81 ÷ 100 = 57.51. Both methods always give the same answer.
In a spreadsheet: =71%*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
57.51 is the 71% share of 81. The remaining 29% is 23.49, and the two parts add back up to 81.

Adding and taking away 71%
Increasing 81 by 71% gives 138.51 and decreasing it by 71% gives 23.49. These do not cancel out: raising 81 by 71% and then lowering the result by 71% ends at 40.1679, because the second 71% is taken of a bigger number.
