Answer #1

\frac{r^2+1}{s^2} can only be rational when s is not equal to zero as any number divided by zero cannot be defined. So that condition has to be incorporated into the statement.

Since division of two rational numbers gives a rational number so this is a rational number. For clear explanation see below.
