We know that 1 serving is equal to 2/3 of a cup.
If we want to find out how many servings are in any number of cups, we should divide the number of cups by the cups per service. For example, if 1 serving = 2 cups, to find how many servings are in 4 cups we would do 4 cups / 2 servings/cup = 2 servings.
The same principle applies here although the numbers are a little trickier. 3 cups / (2/3 servings/cup) = 3 * (3/2) = 9 / 2 or 4.5 servings.
