Answer:
5 and 1/3 cups of water.
Step-by-step explanation:
Set up a proportion like this:
2:3 for the original recipe

w:8 (use w for the unknown water amount)
Set up an equation so that the proportions equal each other. It helps if you write them in fraction form:

Then, divide both sides by 3 to get the amount for w, or water, by itself:
5 and 1/3 = w
