Answer:
it is given that,m,n,p, and q represent nonzero positive integers.
A number between a and b is given by
[tex]\frac{a+b}{2}[/tex]
where, a and b are rational numbers ,having denominator ≠0.
A number between
[tex]\frac{m}{n} \text{and} \frac{p}{q} \text{is equal to}\\\\=\frac{\frac{m}{n} + \frac{p}{q}}{2}\\\\=\frac{mq+np}{2nq}[/tex]
