Question

$\frac{1}{2}=0.5$
It is a terminating decimal because the denominator has a factor as ...........

• A. $0$
• B. $1$
• C. $2$
• D. $6$

Answer 1

The correct option is C $2$

When the prime factorization of the denominator of a fraction has only factors of $2$ and factors of $5$, we say the decimal as terminating decimal.

Here, the denominator has $2$ as a factor and hence it is terminating.

Therefore, $C$ is the correct answer.
