If $\frac{1}{3}$ of $x$ is equal to 4 , then $\frac{1}{6}$ of $x$ is equal to
(A) 3
(B) 4
(C) 2
(D) $\frac{7}{6}$
(E) $\frac{4}{3}$
Since $\frac{1}{3}$ of $x$ is equal to 4 , then $x$ is equal to $3 \times 4$ or 12 . Thus, $\frac{1}{6}$ of $x$ is equal to $12 \div 6=2$.

Alternatively, since $\frac{1}{6}$ is one-half of $\frac{1}{3}$, then $\frac{1}{6}$ of $x$ is equal to one-half of $\frac{1}{3}$ of $x$, which is $4 \div 2$ or 2.

ANSWER: (C)
