\[ \frac{2}{10} + \frac{2}{4} = \frac{7}{10} = 0.7 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{2}{10}\) and \(\frac{2}{4}\) is \(20\). \[ \begin{aligned} \frac{2}{10} + \frac{2}{4} &= \frac{2 \cdot 2}{10 \cdot 2} + \frac{2 \cdot 5}{4 \cdot 5} \\ &= \frac{4 + 10}{20} \\ &= \frac{14}{20} \\&= \frac{7}{10} \end{aligned} \]
