How to work it out

  1. Divide the part by the whole: 30 ÷ 150 = 0.2
  2. Multiply by 100: 0.2 × 100 = 20%
  3. Check: Work backwards: 20% of 150 is 0.2 × 150 = 30.

Another method. As a proportion of part to whole: 30/150 = p/100, so p = 30 × 100 ÷ 150 = 20%. Both methods always give the same answer.

In a spreadsheet: =30/150*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

30 is between a tenth and a quarter of 150. The part that is left, 120, is the other 80%.

Test scores: 30 correct answers out of 150 is a score of 20%, which on a common US grading scale is an F.

Turning it around

If you know that 30 is 20% of a number, you can get that number back: 30 ÷ 0.2 = 150. And 150 as a percentage of 30 is 500%, a different answer, because the whole has changed.
