How to work it out

  1. Divide the part by the whole: 155 ÷ 300 = 0.516667
  2. Multiply by 100: 0.516667 × 100 = 51.6667%
  3. Check: Work backwards: 51.6667% of 300 is 0.516667 × 300 = 155.

Another method. As a proportion of part to whole: 155/300 = p/100, so p = 155 × 100 ÷ 300 = 51.6667%. Both methods always give the same answer.

In a spreadsheet: =155/300*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.
