How to work it out
- Turn the percentage into a decimal: 34 ÷ 100 = 0.34
- Multiply: 0.34 × 81 = 27.54
- Check: Work backwards: 27.54 ÷ 81 × 100 = 34%.
Another method. As a proportion of part to whole: 34/100 = part/81, so part = 34 × 81 ÷ 100 = 27.54. Both methods always give the same answer.
In a spreadsheet: =34%*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.
