To determine whose problem is best modeled by a division expression, let's analyze each question:
-
Julia’s Question:
- The question asks how many one-fourth quart servings of juice are in a cooler that holds 8 quarts.
- We can model this with division: \( 8 \text{ quarts} \div \frac{1}{4} \text{ quart/serving} \). This determines how many servings can be made, which involves dividing the total amount of juice by the size of each serving.
-
Tanveer’s Question:
- The question asks how many quarts of juice are needed to give 8 people each a one-fourth quart serving of juice.
- To find the total amount of juice needed, you would multiply the number of people (8) by the serving size (one-fourth quart): \( 8 \times \frac{1}{4} \). This does not involve division.
Based on this analysis, the correct conclusion is:
- Julia’s problem is best modeled by a division expression, while Tanveer's problem is best modeled by a multiplication expression.
Therefore, the answer is only Julia’s.
