How to work it out

  1. Divide the part by the whole: 20 ÷ 49 = 0.408163
  2. Multiply by 100: 0.408163 × 100 = 40.8163%
  3. Check: Work backwards: 40.8163% of 49 is 0.408163 × 49 = 20.

Another method. As a proportion of part to whole: 20/49 = p/100, so p = 20 × 100 ÷ 49 = 40.8163%. Both methods always give the same answer.

In a spreadsheet: =20/49*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 49. The part that is left, 29, is the other 59.1837%.
