Here's your ratio:
2 water:3 flour (you need two cups of water for every three cups of flour)
Since we're turning that 3 flour into 9 flour, the question we ask ourselves is:
3 x [] = 9
3 x 3 = 9
Now that we know what we're multiplying, we look at the water part:
2 x 3 = []
2 x 3 = 6
Therefore, you need 6 cups of water.
