How to work it out

  1. Divide the part by the whole: 30 ÷ 82 = 0.365854
  2. Multiply by 100: 0.365854 × 100 = 36.5854%
  3. Check: Work backwards: 36.5854% of 82 is 0.365854 × 82 = 30.

Another method. As a proportion of part to whole: 30/82 = p/100, so p = 30 × 100 ÷ 82 = 36.5854%. Both methods always give the same answer.

In a spreadsheet: =30/82*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.
