Answer: 3 cups of water

Explanation

To make 2 pizzas, he needs 3 cups of flour.
To make 8 pizzas, he needs 12 cups of flour.
This is a jump of "times 4".

Quadrupling the original amount of water has us go from 3/4 cups to (3/4)*4 = 3 cups

Another way to find this answer is to solve this proportion
3/0.75 = 12/x
