Final answer:
The question asks for the greatest number of bananas that can be equally shared among Lita and Liza's friends, with a combined total of 12 bananas to distribute. The most a single friend could receive is all 12 bananas if they have only one friend, but this number decreases as more friends are involved.
Step-by-step explanation:
The problem is asking for the largest number of bananas that Lita and Liza can give to their friends so that each friend receives the same amount. Since Lita has 4 bananas and Liza has 8 bananas, the total number of bananas they have together is 4 + 8 = 12 bananas. To determine the biggest number of bananas each friend can get while ensuring each friend gets the same amount, we must find the greatest divisor of 12 that is less than or equal to the number of friends they are sharing with.
If we assume they have at least one friend, the largest number of bananas one friend could receive is 12, which is when they have only one friend. If they have more friends, the number of bananas per friend would need to be a divisor of 12, such as 6, 4, 3, 2 or 1. Without knowing the exact number of friends, we cannot provide a specific value, but the largest possible value under ideal circumstances (one friend) is 12 bananas.
