$$5.3 = \frac{53}{10} = 5.3$$

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of $\frac{5}{1}$ and $\frac{3}{10}$ is $10$. $$\begin{aligned} 5.3 &= \frac{5 \cdot 10}{1 \cdot 10} + \frac{3 \cdot 1}{10 \cdot 1} \\ &= \frac{50 + 3}{10} \\ &= \frac{53}{10} \end{aligned}$$
