Check if the reaction is balanced or unbalanced
Reactants Elements Products
1 Calcium 1
1 Carbon 1
3 Oxygen 3
As the number of atoms in the reactant is the same that the number of atoms in the products we conclude that the reaction is balanced.
So the correct answer is balanced because the total number of oxygen atoms is 3.

We can use a ratio to solve this question. Lets refer to the amount formed by the formula as a serving
1 serving needs 3/8 gal
We want to create 7/9 servings extra, so
1 + 7/9 = 16/7
1 : 3/8
16/7 : x
1/(3/8) = (16/7) / x
8 / 3 = 16x / 7
x = 7/6
He needs to use 7/6 gallons of water.
