How to work it out

  1. Divide the part by the whole: 19 ÷ 40 = 0.475
  2. Multiply by 100: 0.475 × 100 = 47.5%
  3. Check: Work backwards: 47.5% of 40 is 0.475 × 40 = 19.

Another method. As a proportion of part to whole: 19/40 = p/100, so p = 19 × 100 ÷ 40 = 47.5%. Both methods always give the same answer.

In a spreadsheet: =19/40*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

19 is between a quarter and a half of 40. The part that is left, 21, is the other 52.5%.

Test scores: 19 correct answers out of 40 is a score of 47.5%, which on a common US grading scale is an F.

Turning it around
