Question

Which of the following fractions is a terminating decimal?

• A. $\frac{1}{6}$
• B. $\frac{1}{3}$
• C. $\frac{1}{5}$
• D. $\frac{1}{7}$

Answer 1

The correct option is C

$\frac{1}{5}$

To find out whether the given fractions are terminating decimals or not, we need to do division and check.
On dividing, we get

$\frac{1}{6}$ = $0.1\overline{6}$, which is a recurring decimal.

$\frac{1}{3}$ = $0.\overline{3}$, which is a recurring decimal.

$\frac{1}{5}$ = $0.2$, which is a terminating decimal, and hence it is the answer.

$\frac{1}{7}$ =$0.\overline{142857}$, which is also a recurring decimal.
