A. 6 gal. 2 qt. 1 pt.
B. 5 gal. 3 qt. 1 pt.
C. 6 gal. 3 qt. 1 pt.
D. 6 gal. 2 qt. 2 pt.

Answer 1

1 gal    2 qts    3 pts
1 gal    3 qts    7 pts
1 gal    3 qts    3 pts
---------------------------add
3 gal    8 qts    13 pts

1 pt = 0.5 qts...so 12 pts = 12* 0.5 = 6...so now we have :
3 gal   14 qts   1 pt

1 qt = 0.25 gal..so 12 qts = 12 * 0.25 = 3 gallons...so now we have :
6 gal   2 qts   1 pt <===
