How to work it out
- Divide the part by the whole: 30 ÷ 200 = 0.15
- Multiply by 100: 0.15 × 100 = 15%
- Check: Work backwards: 15% of 200 is 0.15 × 200 = 30.
Another method. As a proportion of part to whole: 30/200 = p/100, so p = 30 × 100 ÷ 200 = 15%. Both methods always give the same answer.
In a spreadsheet: =30/200*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.
What the result means
30 is between a tenth and a quarter of 200. The part that is left, 170, is the other 85%.
