Official Solution:

If $$\frac{A}{B} = \frac{3}{4}$$ and $$\frac{C}{A} = \frac{2}{3}$$, what is $$\frac{B}{C} * \frac{B}{A}$$?

A. $$\frac{1}{3}$$
B. $$\frac{1}{2}$$
C. $$\frac{3}{2}$$
D. $$\frac{4}{2}$$
E. $$\frac{8}{3}$$

$$\frac{B}{C} = 2$$, $$\frac{B}{A} = \frac{4}{3}$$. $$\frac{B}{C} * \frac{B}{A} = \frac{8}{3}$$.
