How to work it out
- Turn the percentage into a decimal: 72 ÷ 100 = 0.72
- Multiply: 0.72 × 78 = 56.16
- Check: Work backwards: 56.16 ÷ 78 × 100 = 72%.
Another method. As a proportion of part to whole: 72/100 = part/78, so part = 72 × 78 ÷ 100 = 56.16. Both methods always give the same answer.
In a spreadsheet: =72%*78. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.
