How to work it out

  1. Divide the part by the whole: 78 ÷ 66 = 1.181818
  2. Multiply by 100: 1.181818 × 100 = 118.1818%
  3. Check: Work backwards: 118.1818% of 66 is 1.181818 × 66 = 78.

Another method. As a proportion of part to whole: 78/66 = p/100, so p = 78 × 100 ÷ 66 = 118.1818%. Both methods always give the same answer.

In a spreadsheet: =78/66*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.
