\[ 8 - \frac{7}{9} = \frac{65}{9} = 7.\overline{2} \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{8}{1}\) and \(\frac{-7}{9}\) is \(9\). \[ \begin{aligned} 8 - \frac{7}{9} &= \frac{8 \cdot 9}{1 \cdot 9} + \frac{-7 \cdot 1}{9 \cdot 1} \\ &= \frac{72 + -7}{9} \\ &= \frac{65}{9} \end{aligned} \]
