How to work it out

  1. Divide the part by the whole: 9 ÷ 66 = 0.136364
  2. Multiply by 100: 0.136364 × 100 = 13.6364%
  3. Check: Work backwards: 13.6364% of 66 is 0.136364 × 66 = 9.

Another method. As a proportion of part to whole: 9/66 = p/100, so p = 9 × 100 ÷ 66 = 13.6364%. Both methods always give the same answer.

In a spreadsheet: =9/66*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.
