How to work it out

  1. Divide the part by the whole: 45 ÷ 83 = 0.542169
  2. Multiply by 100: 0.542169 × 100 = 54.2169%
  3. Check: Work backwards: 54.2169% of 83 is 0.542169 × 83 = 45.

Another method. As a proportion of part to whole: 45/83 = p/100, so p = 45 × 100 ÷ 83 = 54.2169%. Both methods always give the same answer.

In a spreadsheet: =45/83*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.
