Answer
K = 0.02: Convert 1 circle.
K = 0.5: Convert 18 circles.
K = 1: Convert 27 circles.
Work Step by Step
$$K = \frac{B}{A} \longrightarrow B = K A$$
$$B + A = 54$$
$$KA + A = 54 \longrightarrow A = \frac{54}{K + 1}$$
For K = 0.02:
$$A = \frac{54}{1.02} = 53$$
$$B = 54 - 53 = 1$$
For K = 0.5:
$$A = \frac{54}{1.5} = 36$$
$$B = 54 - 36 = 18$$
For K = 1:
$$A = \frac{54}{2} = 27$$
$$B = 54 -27 = 27$$
