How to work it out

  1. Divide the part by the whole: 170 ÷ 200 = 0.85
  2. Multiply by 100: 0.85 × 100 = 85%
  3. Check: Work backwards: 85% of 200 is 0.85 × 200 = 170.

Another method. As a proportion of part to whole: 170/200 = p/100, so p = 170 × 100 ÷ 200 = 85%. Both methods always give the same answer.

In a spreadsheet: =170/200*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

170 is more than three quarters of 200. The part that is left, 30, is the other 15%.

Test scores: 170 correct answers out of 200 is a score of 85%, which on a common US grading scale is a B.

Turning it around
