How to work it out

  1. Divide the part by the whole: 3 ÷ 66 = 0.045455
  2. Multiply by 100: 0.045455 × 100 = 4.5455%
  3. Check: Work backwards: 4.5455% of 66 is 0.045455 × 66 = 3.

Another method. As a proportion of part to whole: 3/66 = p/100, so p = 3 × 100 ÷ 66 = 4.5455%. Both methods always give the same answer.

In a spreadsheet: =3/66*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.

What the result means

3 is less than a tenth of 66. The part that is left, 63, is the other 95.4545%.
