\[ \frac{7}{5} + \frac{5}{2} = \frac{39}{10} = 3.9 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{7}{5}\) and \(\frac{5}{2}\) is \(10\). \[ \begin{aligned} \frac{7}{5} + \frac{5}{2} &= \frac{7 \cdot 2}{5 \cdot 2} + \frac{5 \cdot 5}{2 \cdot 5} \\ &= \frac{14 + 25}{10} \\ &= \frac{39}{10} \end{aligned} \]
