Answer:
C. or 3 1/4
Step-by-step explanation:
First, turn all of the amount of fruits (Grapes, Melon, and Pineapple) into an improper fraction.
Grapes: 11/3
Melon: 9/4
Pineapple: 11/4
Then, make a common denominater for each fraction, which is 12, add all of them up. Since you know that the amount of strawberries that Maria uses is 3/8 TIMES the amount of the other fruits, so you multiply the fruits by 3/8.
Grapes: 44/12
Melon: 27/12
Pineapple: 33/12
44/12 + 27/12 + 33/12 times 3/8
= 104/12 times 3/8
= (if you simplify) 13/4 times 1/1 (1/1 = 1)
= 13/4
= 3 1/4
So, the answer is C. 3 1/4
