Answer:
7
Step-by-step explanation:
To solve this problem, find the greatest common factor of the numbers representing the numbers of apples and pears respectively.
 Each box will contain 3 pears and 4 apples.
 And total number of fruits in each box will be 7 fruits.
It's given in the question,
Blake has 64 apples and 48 pears with him.
He has to put equal numbers of each fruit in a box.
To find the greatest number of fruits he can put in a box we will find the greatest common factor (GCF) of the given numbers first.
Therefore, greatest common factor of these numbers = Â = Â
GCF of these numbers tells about the number of boxes that can be prepared.
Now the number of pears that can be put in each box = Â
And the number of apples in each box = Â
    Therefore, each box will contain 3 pears and 4 apples.
    And total number of fruits in each box = 3 + 4 = 7 fruits.
