Since the number in question (0.2012) is in decimal form, it is easiest to determine into which of the 5 given ranges it falls by converting the ranges into decimal form also.

Converting, $\frac{1}{10}$ is $0.1, \frac{1}{5}$ is $0.2, \frac{1}{4}$ is $0.25, \frac{1}{3}$ is $0 . \overline{3}$, and $\frac{1}{2}$ is 0.5 .

Since 0.2012 is greater than 0.2 but less than 0.25 , it is between $\frac{1}{5}$ and $\frac{1}{4}$.

ANsWER: (C)
The number 0.2012 is between
(A) 0 and $\frac{1}{10}$
(B) $\frac{1}{10}$ and $\frac{1}{5}$
(C) $\frac{1}{5}$ and $\frac{1}{4}$
(D) $\frac{1}{4}$ and $\frac{1}{3}$
(E) $\frac{1}{3}$ and $\frac{1}{2}$
