How to work it out

  1. Divide the part by the whole: 40 ÷ 57 = 0.701754
  2. Multiply by 100: 0.701754 × 100 = 70.1754%
  3. Check: Work backwards: 70.1754% of 57 is 0.701754 × 57 = 40.

Another method. As a proportion of part to whole: 40/57 = p/100, so p = 40 × 100 ÷ 57 = 70.1754%. Both methods always give the same answer.

In a spreadsheet: =40/57*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

40 is more than half but less than three quarters of 57. The part that is left, 17, is the other 29.8246%.
