How to work it out

  1. Divide the part by the whole: 900 ÷ 1000 = 0.9
  2. Multiply by 100: 0.9 × 100 = 90%
  3. Check: Work backwards: 90% of 1000 is 0.9 × 1000 = 900.

Another method. As a proportion of part to whole: 900/1000 = p/100, so p = 900 × 100 ÷ 1000 = 90%. Both methods always give the same answer.

In a spreadsheet: =900/1000*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

900 is more than three quarters of 1000. The part that is left, 100, is the other 10%.

Test scores: 900 correct answers out of 1000 is a score of 90%, which on a common US grading scale is an A.

Turning it around

If you know that 900 is 90% of a number, you can get that number back: 900 ÷ 0.9 = 1000. And 1000 as a percentage of 900 is 111.1111%, a different answer, because the whole has changed.
