\[ \frac{-16}{4} - \frac{30}{-5} = 2 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{-16}{4}\) and \(\frac{-30}{-5}\) is \(20\). \[ \begin{aligned} \frac{-16}{4} - \frac{30}{-5} &= \frac{-16 \cdot 5}{4 \cdot 5} + \frac{-30 \cdot -4}{-5 \cdot -4} \\ &= \frac{-80 + 120}{20} \\ &= \frac{40}{20} \\&= 2 \end{aligned} \]
