If the degree of the polynomial $q(x)$ is more than the degree of the polynomial $p(x)$, than the rational fraction $\frac{{p(x)}}{{q(x)}}$ is called as proper fraction.
Mathematically,
Degree of the polynomial, $q(x) \geqslant p(x)$.
Examples of proper fraction $$\frac{{x + 1}}{{{x^2} + 3x + 2}}\quad ,\quad \frac{{{x^2} + 5}}{{{x^3} + 2{x^2} + 5x + 2}}$$
