How to work it out
- Divide the part by the whole: 42 ÷ 42 = 1
- Multiply by 100: 1 × 100 = 100%
- Check: Work backwards: 100% of 42 is 1 × 42 = 42.
Another method. As a proportion of part to whole: 42/42 = p/100, so p = 42 × 100 ÷ 42 = 100%. Both methods always give the same answer.
In a spreadsheet: =42/42*100. Dividing the wrong way round (whole ÷ part) gives a different answer. The number after “of” is always the whole, so it goes on the bottom.
