Answer:
3 3/4 cups
Step-by-step explanation:
first we need to see how many cups of bananas are in each smoothie
2 1/2 divided by 4 = 0.625
now that we know how many cups of bananas are in each smoothie we can add that twice to the amount of bananas needed to make four smoothies
0.625 x 2 = 1. 25 or 1 1/4
then add that to the 2 1/2
1 1/4 + 2 1/2 = 3.75 or 3 3/4 cups
another way to do it is to divide the 4 cups then add that to the 2 1/2 cups:
2 1/2 divided by 2 = 1.25 or 1 1/4 cups
then add that to the 2 1/2 cups:
2 1/2 + 1 1/4 = 3.75 or 3 3/4 cups
