How to work it out

  1. Divide the part by the whole: 40 ÷ 89 = 0.449438
  2. Multiply by 100: 0.449438 × 100 = 44.9438%
  3. Check: Work backwards: 44.9438% of 89 is 0.449438 × 89 = 40.

Another method. As a proportion of part to whole: 40/89 = p/100, so p = 40 × 100 ÷ 89 = 44.9438%. Both methods always give the same answer.

In a spreadsheet: =40/89*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.
