State whether the following rational number has a terminating decimal expansion or not. If it does,find it: $\frac{19}{8}$

(A) rational number $\frac{p}{q}$ has a terminating decimal expansion if the prime factorization of the denominator $q$ is of the form $2^n \times 5^m$,where $n$ and $m$ are non-negative integers.
Here,the denominator is $8 = 2^3 = 2^3 \times 5^0$.
Since the denominator is in the form $2^n \times 5^m$,the rational number $\frac{19}{8}$ has a terminating decimal expansion.
To find the decimal expansion,we can divide $19$ by $8$:
$19 \div 8 = 2.375$.
