How to work it out

  1. Divide the part by the whole: 91 ÷ 78 = 1.166667
  2. Multiply by 100: 1.166667 × 100 = 116.6667%
  3. Check: Work backwards: 116.6667% of 78 is 1.166667 × 78 = 91.

Another method. As a proportion of part to whole: 91/78 = p/100, so p = 91 × 100 ÷ 78 = 116.6667%. Both methods always give the same answer.

In a spreadsheet: =91/78*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.
