How to work it out

  1. Divide the part by the whole: 28 ÷ 45 = 0.622222
  2. Multiply by 100: 0.622222 × 100 = 62.2222%
  3. Check: Work backwards: 62.2222% of 45 is 0.622222 × 45 = 28.

Another method. As a proportion of part to whole: 28/45 = p/100, so p = 28 × 100 ÷ 45 = 62.2222%. Both methods always give the same answer.

In a spreadsheet: =28/45*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.
