The correct option is B 4
We need to find the number of apples packed in each box if we pack 28 apples in 7 boxes.
Let us do repeated subtraction to find the number of apples in each box.
28 - 7 = 21
21 - 7 = 14
14 - 7 = 7
7 - 7 = 0
So, after 4 times all the apples were packed in boxes.
Thus, 4 apples are packed in each box.
