An aquarium tank is 1/6 full of water. When 2 gallons of water are added, the tank becomes 5/12 full. What is the total capacity of the aquarium tank, in gallons?
Let the capacity = C
So
(1/6) C + 2 = (5/12) C
2 = (5/12) C - (1/6)C
2 = (5/12) C = (2/12) C
2 = (3/12) C
2 = (1/4) C
2 / (1/4) = C
8 = C
