\[ -8 + \frac{48}{70} = - \frac{256}{35} = -7.3\overline{142857} \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{-8}{1}\) and \(\frac{48}{70}\) is \(70\). \[ \begin{aligned} -8 + \frac{48}{70} &= \frac{-8 \cdot 70}{1 \cdot 70} + \frac{48 \cdot 1}{70 \cdot 1} \\ &= \frac{-560 + 48}{70} \\ &= \frac{-512}{70} \\&= - \frac{256}{35} \end{aligned} \]
