To work this out, we want to find the Lowest Common Multiple of 6 and 12
This is the smallest number that fits in both
6 x 2 = 12
12 x 1 = 12
11/12 is already over 12 so we don't need to do anything
5/6 is not - to convert it, we multiply the top and the bottom by 2
5 x 2 = 10
10/12 or 11/12
10 is smaller than 11
Therefore 5/6 is smaller than 11/12
5/6 < 11/12
11/12 is greater
