How to work it out
- Turn the percentage into a decimal: 83 ÷ 100 = 0.83
- Multiply: 0.83 × 42 = 34.86
- Check: Work backwards: 34.86 ÷ 42 × 100 = 83%.
Another method. As a proportion of part to whole: 83/100 = part/42, so part = 83 × 42 ÷ 100 = 34.86. Both methods always give the same answer.
In a spreadsheet: =83%*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.

Adding and taking away 83%
