How to work it out

  1. Divide the part by the whole: 30 ÷ 85 = 0.352941
  2. Multiply by 100: 0.352941 × 100 = 35.2941%
  3. Check: Work backwards: 35.2941% of 85 is 0.352941 × 85 = 30.

Another method. As a proportion of part to whole: 30/85 = p/100, so p = 30 × 100 ÷ 85 = 35.2941%. Both methods always give the same answer.

In a spreadsheet: =30/85*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.
