How to work it out
- Turn the percentage into a decimal: 57 ÷ 100 = 0.57
- Multiply: 0.57 × 42 = 23.94
- Check: Work backwards: 23.94 ÷ 42 × 100 = 57%.
Another method. As a proportion of part to whole: 57/100 = part/42, so part = 57 × 42 ÷ 100 = 23.94. Both methods always give the same answer.
In a spreadsheet: =57%*42. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.
