How to work it out
- Divide the part by the whole: 45 ÷ 45 = 1
- Multiply by 100: 1 × 100 = 100%
- Check: Work backwards: 100% of 45 is 1 × 45 = 45.
Another method. As a proportion of part to whole: 45/45 = p/100, so p = 45 × 100 ÷ 45 = 100%. Both methods always give the same answer.
In a spreadsheet: =45/45*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.
