Final answer:
To find the largest number of bananas each friend can receive, divide the total number of bananas by the number of friends.
Step-by-step explanation:
To find the largest number of bananas each friend can receive, we need to divide the total number of bananas that Lita and Liza have by the number of friends they have. Lita has 4 bananas and Liza has 8 bananas, so the total number of bananas is 4 + 8 = 12. Let's say they have n number of friends. The largest number of bananas each friend can receive is given by the equation 12 / n.
For example, if they have 2 friends, then the largest number of bananas each friend can receive is 12 / 2 = 6 bananas. If they have 3 friends, then the largest number of bananas each friend can receive is 12 / 3 = 4 bananas.
