How to work it out
- Turn the percentage into a decimal: 27 ÷ 100 = 0.27
- Multiply: 0.27 × 81 = 21.87
- Check: Work backwards: 21.87 ÷ 81 × 100 = 27%.
Another method. As a proportion of part to whole: 27/100 = part/81, so part = 27 × 81 ÷ 100 = 21.87. Both methods always give the same answer.
In a spreadsheet: =27%*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.
