There are 2 circles for each square. Why? Well, in the diagram, we can count out that there are 6 squares and 12 circles. Because this represents a proportion, we can divide 12 by 6 to get 2. Since 12 / 6 = 2, that means that to equal up to 6 squares, there would have to be 2 circles for each square. If you need help, let me know and I will gladly assist you.
