The diagram you mentioned, which has 5 ovals containing 7 squares, is best illustrated by the division problem 35 divided by 7 = 5.
Here's the reasoning:
- The 5 ovals can represent the 5 groups.
- The 7 squares can represent the total items (in this case, 35).
When dividing 35 by 7, you're determining how many groups of 7 can be made from 35, which equals 5. Hence, the diagram fits this division problem well.
