Answer:
720 Quarts
Step-by-step explanation:

cross multiply

now that they are both divided by 180, we can eliminate it

Answer:
1. a=3, b = 2, c = 1.
2. a=2, b=3, c=4, d=6.
3. a = 9, b = 3.
Step-by-step explanation:
1. 3 | 21 is a counterexample because 3 does not divide into 2 or 1.
2. 23 | 46 is a counterexample because 2 does not divide into 3.
3. 9 | 3^2 is a counterexample because 9 does not divide into 3.
11/15-2/5
Multiply 2 and 5 to get a common denominator of 15
11/15-6/15
=4/15
