Question #N886

If $\frac{x}{y} = 2$ and $\frac{y}{z} = 3$, what is the value of $\frac{x}{z}$?
A. $\frac{1}{6}$
B. $\frac{2}{3}$
C. 2
D. 6

Correct Answer is: D

We can multiply the two given equations together: $\frac{x}{y} \cdot \frac{y}{z} = 2 \cdot 3$. The y terms cancel, leaving $\frac{x}{z} = 6$.
