Final answer:
The three word problems that can be represented by a division equation with an unknown quotient are A) number of bags for cookies, B) apples shared among friends, and D) number of student groups in a class.
Step-by-step explanation:
The three word problems from the selection that can be represented by a division equation with an unknown quotient are:
- A. "There are 24 cookies, and each bag can hold 6 cookies. How many bags are needed?"
- B. "Sarah has 16 apples and wants to share them equally among her 4 friends. How many apples will each friend get?"
- D. "There are 18 students in a class, and the teacher wants to divide them into groups of 3. How many groups will there be?"
These problems involve dividing a total number by a smaller number to find out how many times the smaller number goes into the larger number, which represents the unknown quotient.
