Let's compose a problem where we have two groups of items, and we need to find out how many groups of a certain size can be formed from their total amount.
Problem: In the first basket, there are 45 apples, and in the second basket, there are 35 apples. All the apples are to be packed into boxes, with each box holding 5 apples. How many boxes will be needed?
The expression (45 + 35) represents the total number of apples from both baskets. Dividing this sum by 5 gives us the number of boxes required, as each box holds 5 apples.
Answer: A problem can be formulated as described above.
