Final answer:
Karen can make 4 servings of 1/3 cup each.
Step-by-step explanation:
To find out how many 1/3 cup servings Karen can make with 7/8 cup of ice cream, we need to divide the total amount of ice cream by the amount of ice cream needed for each serving.
There are two steps to do this. First, we convert 7/8 cup of ice cream to an equivalent fraction with a denominator of 3 by multiplying the numerator and denominator by 3: (7/8) * (3/3) = 21/24 cup.
Next, we divide 21/24 cup by 1/3 cup: (21/24) ÷ (1/3) = 63/24 ÷ 8/24 = 63/8 = 7 7/8 servings. So Karen can make C) 4 servings of 1/3 cup each.
