How to work it out

  1. Divide the part by the whole: 40 ÷ 150 = 0.266667
  2. Multiply by 100: 0.266667 × 100 = 26.6667%
  3. Check: Work backwards: 26.6667% of 150 is 0.266667 × 150 = 40.

Another method. As a proportion of part to whole: 40/150 = p/100, so p = 40 × 100 ÷ 150 = 26.6667%. Both methods always give the same answer.

In a spreadsheet: =40/150*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

40 is between a quarter and a half of 150. The part that is left, 110, is the other 73.3333%.

Test scores: 40 correct answers out of 150 is a score of 26.6667%, which on a common US grading scale is an F.

If you know that 40 is 26.6667% of a number, you can get that number back: 40 ÷ 0.266667 = 150. And 150 as a percentage of 40 is 375%, a different answer, because the whole has changed.
