Answer:
4 servings
Explanation:
If a serving of juice is 1/8 of the pitcher, we know that a full pitcher is capable of 8 servings, because 8 servings would be 8/8 of the picher, that is, the whole pitcher.
As the picher is 1/2 full of juice, it is half full, so it can serve only half of its full capacity, so half of 8 servings: 4 servings.
