To solve this problem, we can use division.
a. To find out how many boxes can be filled with 987 DVDs if each box fits 22 DVDs, we divide 987 by 22:
So, they can fill 44 boxes.
b. Next, we need to calculate how many DVDs would be left over after filling the boxes. We can find the remainder of the division:
First, calculate the total number of DVDs packed in the 44 boxes:
Now, subtract this from the total number of DVDs:
So, there would be 19 DVDs left over.
To summarize: a. 44 b. 19
