How to work it out

  1. Divide the part by the whole: 10 ÷ 300 = 0.033333
  2. Multiply by 100: 0.033333 × 100 = 3.3333%
  3. Check: Work backwards: 3.3333% of 300 is 0.033333 × 300 = 10.

Another method. As a proportion of part to whole: 10/300 = p/100, so p = 10 × 100 ÷ 300 = 3.3333%. Both methods always give the same answer.

In a spreadsheet: =10/300*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

10 is less than a tenth of 300. The part that is left, 290, is the other 96.6667%.

Test scores: 10 correct answers out of 300 is a score of 3.3333%, which on a common US grading scale is an F.

Turning it around

If you know that 10 is 3.3333% of a number, you can get that number back: 10 ÷ 0.033333 = 300. And 300 as a percentage of 10 is 3,000%, a different answer, because the whole has changed.
