How to work it out

  1. Divide the part by the whole: 30 ÷ 61 = 0.491803
  2. Multiply by 100: 0.491803 × 100 = 49.1803%
  3. Check: Work backwards: 49.1803% of 61 is 0.491803 × 61 = 30.

Another method. As a proportion of part to whole: 30/61 = p/100, so p = 30 × 100 ÷ 61 = 49.1803%. Both methods always give the same answer.

In a spreadsheet: =30/61*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.
