Compare the two sets shown above:

a. Describe the ratio of shaded circles to unshaded circles in each set.

b. How is this comparison different from describing the ratio of shaded circles to all of the circles in each set?

c. How could you compare the ratio of shaded circles in Set A with the ratio of shaded circles in Set B?

Talking about the relationships between fractions helps you think about how these relationships can be written symbolically. If you try to use the symbols first, you may get lost in the numbers. Conversation about mathematical concepts helps foster a deeper understanding of these concepts.
