\[ 7 - \frac{3}{55} = \frac{382}{55} = 6.9\overline{45} \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{7}{1}\) and \(\frac{-3}{55}\) is \(55\). \[ \begin{aligned} 7 - \frac{3}{55} &= \frac{7 \cdot 55}{1 \cdot 55} + \frac{-3 \cdot 1}{55 \cdot 1} \\ &= \frac{385 + -3}{55} \\ &= \frac{382}{55} \end{aligned} \]
