Final answer:
To find the number of full servings, divide the total amount of punch by the serving size. In this case, Ana's class can make 25 full servings of punch.
Step-by-step explanation:
To find the number of full servings, we need to divide the total amount of punch by the serving size.
In this case, the class is going to pour 12-ounce servings of punch.
Since there are 25 students in Ana's class, we can multiply the number of students by the serving size to find the total amount of punch needed:
25 students x 12 ounces/student = 300 ounces
Next, we can divide the total amount of punch by the serving size to find the number of full servings:
300 ounces / 12 ounces/serving = 25 servings
Therefore, Ana's class can make 25 full servings of punch.
