Question #N657
If $\frac{x}{y} = 3$ and $\frac{y}{z} = 2$, what is the value of $\frac{x}{z}$?
A. $\frac{1}{6}$
B. $\frac{3}{2}$
C. $\frac{5}{3}$
D. 6
Correct Answer is: D
We can multiply the two given equations together: $\frac{x}{y} \cdot \frac{y}{z} = 3 \cdot 2$. The $y$ terms cancel, leaving us with $\frac{x}{z} = 6$.
