Question
Without actual division, find the following rational numbers are terminating decimals. $\frac{5}{12}$
✓
Answer
$\frac{5}{12}$ Denominator of $\frac{5}{12}$ is $12 $. And, $12=2^2 \times 3$ So, $12$ has a prime factor $3 ,$ which is other than $2$ and $5$ . Thus, $\frac{5}{12}$ is not a terminating decimal.
