Answer:
2 cups of sugar to 6 cups of water
Step-by-step explanation:
3 cups of sugar to 9 cups of water is our starting point.
If we plan to use only 2 cups of sugar, which is 2/3 of 3 cups,
multiply both quantities in "3 cups of sugar to 9 cups of water" by 2/3:
(2/3)(3 cups of sugar) to (2/3)(9 cups of water), obtaining:
2 cups of sugar to 6 cups of water.
Note that the ratio here is 3:9, which reduces to 1:3: 1 cup of sugar to 3 cups of water.
