How to work it out
- Turn the percentage into a decimal: 9 ÷ 100 = 0.09
- Multiply: 0.09 × 87 = 7.83
- Check: Work backwards: 7.83 ÷ 87 × 100 = 9%.
Another method. As a proportion of part to whole: 9/100 = part/87, so part = 9 × 87 ÷ 100 = 7.83. Both methods always give the same answer.
In a spreadsheet: =9%*87. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.
