You are right, you could just take 67-17 , then tack on the 4/7
= 50 4/7
On the other hand if you had
67 - (17 4/7) then you would have to take common denominators , etc
67 4/7 - 17
How do do this one? Do I need to bother because the fraction has nothing to subtract with but the whole numbers do

4/7 - 0 = 4/7
67 4/7 - 17 = 50 4/7
67 4/7 - 17 = 50 4/7
