Arithmetic Grade Four

It is easy to tell that the following fractions are in order because they all have the same denominator.


     1      2      3      4      5      6      7
    ---    ---    ---    ---    ---    ---    ---
     8      8      8      8      8      8      8

When the denominators are different it takes a little more work to tell if a group of fractions are in order or not. Consider the following list.


    2      2      2      2      2      2      2
   ---    ---    ---    ---    ---    ---    ---
    15     11     9      7      5      4      3

With the numerators all equal it is a bit easier to tell that these are in order.

With the numerators and denominators all mixed up it takes even more effort to tell if a group of numbers are i order.


    2     4     3     5     1     3
   ---   ---   ---   ---   ---   ---
    9     11    8     13    2     5

These fractions are in order, by the way.
