How to work it out

  1. Divide the part by the whole: 34 ÷ 80 = 0.425
  2. Multiply by 100: 0.425 × 100 = 42.5%
  3. Check: Work backwards: 42.5% of 80 is 0.425 × 80 = 34.

Another method. As a proportion of part to whole: 34/80 = p/100, so p = 34 × 100 ÷ 80 = 42.5%. Both methods always give the same answer.

In a spreadsheet: =34/80*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

34 is between a quarter and a half of 80. The part that is left, 46, is the other 57.5%.

Test scores: 34 correct answers out of 80 is a score of 42.5%, which on a common US grading scale is an F.
