Final answer:
To find the ratio of diced onion to cooked chicken in the recipe for chicken noodle soup, set up a proportion using the quantities of each ingredient. The ratio of diced onion to cooked chicken is 4:1.
Step-by-step explanation:
To find the ratio of diced onion to cooked chicken, we need to determine the quantities of each ingredient required for 16 servings. Let's assume the recipe calls for x cups of diced onion and y cups of cooked chicken. Since the ratio is asking for the ratio of onion to chicken, the ratio can be represented as x:y.
We can set up a proportion using the information given:
x cups / y cups = 4 cups / 1 quart
Cross-multiplying, we get xy = 4y cups. Dividing both sides by y, we get x/y = 4. Therefore, the ratio of diced onion to cooked chicken is 4:1. Hence, the correct answer is option C) 4:1.
