How to work it out

  1. Divide the part by the whole: 9 ÷ 55 = 0.163636
  2. Multiply by 100: 0.163636 × 100 = 16.3636%
  3. Check: Work backwards: 16.3636% of 55 is 0.163636 × 55 = 9.

Another method. As a proportion of part to whole: 9/55 = p/100, so p = 9 × 100 ÷ 55 = 16.3636%. Both methods always give the same answer.

In a spreadsheet: =9/55*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

9 is between a tenth and a quarter of 55. The part that is left, 46, is the other 83.6364%.
