a water tank is one-eighth full. it is three-fourths full when forty-two gallons of water are added to the tank. how much does the tank hold?
+37084 Well, it basically tells you that 3/4 - 1/8 = 42 Gallons
6/8 - 1/8 = 42 gallons
5/8 tank = 42 gallons multiply both sides by 8/5
1 tank = 42 (8/5) gallons = 67.2 gallons
