(b) write the ratio of diamonds to emeralds.
□:□

Explanation:

Step1: Identify quantities

From the table, diamonds = 3, emeralds = 4.

Step2: Determine the ratio

The ratio of diamonds to emeralds is the number of diamonds compared to emeralds. So, diamonds : emeralds = 3 : 4. For the diagram, we can represent the ratio using blocks. Each block can represent a unit. So, for diamonds, we have 3 blocks, and for emeralds, 4 blocks. The diagram structure would have the top label as "Ratio of Diamonds to Emeralds", with the left part (diamonds) having 3 units and the right part (emeralds) having 4 units.

Answer:

(a) Diagram: Top label "Ratio of Diamonds to Emeralds", left (diamonds) with 3 blocks, right (emeralds) with 4 blocks. (b) The ratio of diamonds to emeralds is $\boldsymbol{3 : 4}$.
