How to work it out
- Turn the percentage into a decimal: 24 ÷ 100 = 0.24
- Multiply: 0.24 × 81 = 19.44
- Check: Work backwards: 19.44 ÷ 81 × 100 = 24%.
Another method. As a proportion of part to whole: 24/100 = part/81, so part = 24 × 81 ÷ 100 = 19.44. Both methods always give the same answer.
In a spreadsheet: =24%*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.
