Answer:
1 3/12
Explanation:
Oh wait i could read #5 so you make them all have 12 as the denominator then do 78 4/12 - 77 1/12 and you get 1 1/4 or 1 3/12 so then you do 1 3/12 MINUS 77 1/12 and you should get 75 10/12 which is CORRECCTTTTT
THESE ARE THE THREE IN THE TEXT ORDER IN CASE U NEED TO SEE
78 4/12
77 1/12
75 10/12
EVERYTHING IS CORRECTTTTTTTTTTTTTTTTTTTTTT
