An aqarium 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?
Call 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 (4/1) = C = 8 gallons
