\[ 2.2 = \frac{11}{5} = 2.2 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{2}{1}\) and \(\frac{2}{10}\) is \(10\). \[ \begin{aligned} 2.2 &= \frac{2 \cdot 10}{1 \cdot 10} + \frac{2 \cdot 1}{10 \cdot 1} \\ &= \frac{20 + 2}{10} \\ &= \frac{22}{10} \\&= \frac{11}{5} \end{aligned} \]
