How to work it out

  1. Divide the part by the whole: 45 ÷ 57 = 0.789474
  2. Multiply by 100: 0.789474 × 100 = 78.9474%
  3. Check: Work backwards: 78.9474% of 57 is 0.789474 × 57 = 45.

Another method. As a proportion of part to whole: 45/57 = p/100, so p = 45 × 100 ÷ 57 = 78.9474%. Both methods always give the same answer.

In a spreadsheet: =45/57*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.
