How to work it out

  1. Divide the part by the whole: 10 ÷ 78 = 0.128205
  2. Multiply by 100: 0.128205 × 100 = 12.8205%
  3. Check: Work backwards: 12.8205% of 78 is 0.128205 × 78 = 10.

Another method. As a proportion of part to whole: 10/78 = p/100, so p = 10 × 100 ÷ 78 = 12.8205%. Both methods always give the same answer.

In a spreadsheet: =10/78*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.

What the result means

10 is between a tenth and a quarter of 78. The part that is left, 68, is the other 87.1795%.
