How to work it out

  1. Divide the part by the whole: 210 ÷ 300 = 0.7
  2. Multiply by 100: 0.7 × 100 = 70%
  3. Check: Work backwards: 70% of 300 is 0.7 × 300 = 210.

Another method. As a proportion of part to whole: 210/300 = p/100, so p = 210 × 100 ÷ 300 = 70%. Both methods always give the same answer.

In a spreadsheet: =210/300*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

210 is more than half but less than three quarters of 300. The part that is left, 90, is the other 30%.

Test scores: 210 correct answers out of 300 is a score of 70%, which on a common US grading scale is a C.

Turning it around

If you know that 210 is 70% of a number, you can get that number back: 210 ÷ 0.7 = 300. And 300 as a percentage of 210 is 142.8571%, a different answer, because the whole has changed.
