Final answer:
To write 3/4 cup per 1/2 serving as a unit rate, divide the numerator by the denominator to find the value of 1 serving (1 1/2 cups). Then, write the unit rate as 1/2 cup per 1 serving. Therefore, the correct choice is B. 1/2 cup per serving.
Step-by-step explanation:
To convert 3/4 cup per 1/2 serving to a unit rate, we need to find out how much is in one serving. First, we need to understand that if we have 3/4 cup for every 1/2 of a serving, for a full serving (which is double 1/2), we need to double the 3/4 cup. To write 3/4 cup per 1/2 serving as a unit rate, we need to find the equivalent unit rate.
- First, divide the numerator by the denominator to find the value of 1 serving: 3/4 ÷ 1/2 = 3/4 × 2/1 = 3/2 = 1 1/2 cups.
- Next, write the unit rate: 3/4 cup per 1 1/2 cups.
- Finally, simplify the unit rate: 3/4 cup per 1 1/2 cups is equivalent to 1/2 cup per 1 serving.
Therefore, the correct choice is B. 1/2 cup per serving.
