The first number becomes the numerator and the second number becomes the denominator. 2 is 1/3 of 6 because when one writes 2/6 it can be simplified to 1/3. 40 cannot be expressed as a true fraction until one has a second number to be the denominator in 40/X The only way to express 40 as a fraction is to write it as 40/1.
