$\Large{\bf{\green{\mathfrak{\dag{\underline{\underline{Explanation:-}}}}}}}$

A rational number is integersin p/q where q is not equal to 0.

m = p / q  = 4/5  = 0.8

n = r / s =  9/2  or 4.5

$\sf{sum}$ = $\frac{4}{5} + \frac{9}{2} = \frac{53}{10}$

$\sf{product}$ = $\frac{36}{10}$

$\sf{difference}$ = $\frac{9}{2} - \frac{4}{5} = \frac{36}{10}$

$\sf{division}$ = $\frac{9}{2} ÷  \frac{4}{5} = \frac{45}{8}  = 5.625$
