How to work it out
- Turn the percentage into a decimal: 86 ÷ 100 = 0.86
- Multiply: 0.86 × 18 = 15.48
- Check: Work backwards: 15.48 ÷ 18 × 100 = 86%.
Another method. As a proportion of part to whole: 86/100 = part/18, so part = 86 × 18 ÷ 100 = 15.48. Both methods always give the same answer.
In a spreadsheet: =86%*18. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.
