How to work it out

  1. Divide the part by the whole: 100 ÷ 150 = 0.666667
  2. Multiply by 100: 0.666667 × 100 = 66.6667%
  3. Check: Work backwards: 66.6667% of 150 is 0.666667 × 150 = 100.

Another method. As a proportion of part to whole: 100/150 = p/100, so p = 100 × 100 ÷ 150 = 66.6667%. Both methods always give the same answer.

In a spreadsheet: =100/150*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

100 is more than half but less than three quarters of 150. The part that is left, 50, is the other 33.3333%.

Test scores: 100 correct answers out of 150 is a score of 66.6667%, which on a common US grading scale is a D.

Turning it around

If you know that 100 is 66.6667% of a number, you can get that number back: 100 ÷ 0.666667 = 150. And 150 as a percentage of 100 is 150%, a different answer, because the whole has changed.
