GCD(5,9) = 45
4/5 = 36/45
8/9 = 40/45 Now, we have a common denominator.
36 < 40. So, 36/45 < 40/45. Therefore, 4/5 < 8/9.
Of course, you could come immediately to this same conclusion observing that
4/5 = 0.8
8/9 = 0.8888888.....
So, 4/5 < 8/9

Here is a quick approach:
8/9 = (4+4)/(5+4) > 4/5, since 4/4 > 4/5.

This can be solved using common denominators.
4/5 = 36/45
8/9 = 40/45
Clearly 36/45 < 40/45, thus 4/5 < 8/9.

4/5 = 36/45 & 8/9 = 40/45
36/45 < 40/45
=> 4/5 < 8/9
