Explanation:

Step1: Identify the ratio

We need to find the number of blue rows per green row. The number of blue rows is 5, and the number of green rows is 2. So we calculate the ratio of blue rows to green rows, which is $ \frac{5}{2} $.

Step2: Simplify the fraction

$ \frac{5}{2} $ is equal to $ 2\frac{1}{2} $ when converted to a mixed number.

Answer:

B. $ 2\frac{1}{2} $ rows of blue yarn per row of green yarn
