Question 4

Decimal form of rational numbers can be classified into two types.
Let $$a$$ be a rational number whose decimal expansion terminates. Then $$a$$ can be expressed in the form $$\frac{p}{q}$$, where $$p$$ and $$q$$ are co-prime and the prime factorisation of $$q$$ is of the form $$2^{n} \cdot 5^{m}$$, where $$\{n}, m$$ are non-negative integers and vice-versa.
Let $$a=\frac{p}{q}$$ be a rational number, such that the prime factorisation of $$q$$ is not of the form $$2^{n} 5^{m}$$, where $$n$$ and $$m$$ are non-negative integers. Then $$a$$ has a non-terminating repeating decimal expansion. 
Based on the above information, answer the following:
Which of the following rational numbers have a terminating decimal expansion?

Question 5

Decimal form of rational numbers can be classified into two types.
Let $$a$$ be a rational number whose decimal expansion terminates. Then $$a$$ can be expressed in the form $$\frac{p}{q}$$, where $$p$$ and $$q$$ are co-prime and the prime factorisation of $$q$$ is of the form $$2^{n} \cdot 5^{m}$$, where $$\dot{n}, m$$ are non-negative integers and vice-versa.
Let $$a=\frac{p}{q}$$ be a rational number, such that the prime factorisation of $$q$$ is not of the form $$2^{n} 5^{m}$$, where $$n$$ and $$m$$ are non-negative integers. Then $$a$$ has a non-terminating repeating decimal expansion.
Based on the above information, answer the following:
$$\frac{23}{\left(2^{3} 	imes 5^{3}ight)}=$$
