Final answer:
To serve 10 people, 10 cups of rice are needed. To serve 45 people, 45 cups of rice are needed.
Step-by-step explanation:
To determine how many people 10 cups of rice will serve, we need to know how many cups of rice each person will eat. Let's assume each person eats 1 cup of rice. So, 10 cups of rice will serve 10 people. For the second question, we need to find out how many cups of rice are needed to serve 45 people. Let's assume each person still eats 1 cup of rice. Therefore, we would need 45 cups of rice to serve 45 people.
