Problem: if henry were to add 6 gallons of water to a tank that is already 3 / 4 full of water , the tank would be 7 / 8 full . how many gallons of water would the tank hold if it were full ?
Rationale: "7 / 8 x - 3 / 4 x = 6 galls 1 / 8 * x = 6 gallons x = 48 gallons answer b"
annotated_formula: multiply(6, divide(const_1, subtract(divide(7, 8), divide(3, 4))))
