How to work it out

  1. Divide the part by the whole: 20 ÷ 45 = 0.444444
  2. Multiply by 100: 0.444444 × 100 = 44.4444%
  3. Check: Work backwards: 44.4444% of 45 is 0.444444 × 45 = 20.

Another method. As a proportion of part to whole: 20/45 = p/100, so p = 20 × 100 ÷ 45 = 44.4444%. Both methods always give the same answer.

In a spreadsheet: =20/45*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

20 is between a quarter and a half of 45. The part that is left, 25, is the other 55.5556%.
