How to work it out

  1. Divide the part by the whole: 78 ÷ 64 = 1.21875
  2. Multiply by 100: 1.21875 × 100 = 121.875%
  3. Check: Work backwards: 121.875% of 64 is 1.21875 × 64 = 78.

Another method. As a proportion of part to whole: 78/64 = p/100, so p = 78 × 100 ÷ 64 = 121.875%. Both methods always give the same answer.

In a spreadsheet: =78/64*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.

What the result means
