How to work it out

  1. Divide the part by the whole: 20 ÷ 300 = 0.066667
  2. Multiply by 100: 0.066667 × 100 = 6.6667%
  3. Check: Work backwards: 6.6667% of 300 is 0.066667 × 300 = 20.

Another method. As a proportion of part to whole: 20/300 = p/100, so p = 20 × 100 ÷ 300 = 6.6667%. Both methods always give the same answer.

In a spreadsheet: =20/300*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 less than a tenth of 300. The part that is left, 280, is the other 93.3333%.
