How to work it out

  1. Divide the part by the whole: 20 ÷ 63 = 0.31746
  2. Multiply by 100: 0.31746 × 100 = 31.746%
  3. Check: Work backwards: 31.746% of 63 is 0.31746 × 63 = 20.

Another method. As a proportion of part to whole: 20/63 = p/100, so p = 20 × 100 ÷ 63 = 31.746%. Both methods always give the same answer.

In a spreadsheet: =20/63*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 63. The part that is left, 43, is the other 68.254%.
