\[ 30 - 0.5 = \frac{59}{2} = 29.5 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{30}{1}\) and \(\frac{-5}{10}\) is \(10\). \[ \begin{aligned} 30 - 0.5 &= \frac{30 \cdot 10}{1 \cdot 10} + \frac{-5 \cdot 1}{10 \cdot 1} \\ &= \frac{300 + -5}{10} \\ &= \frac{295}{10} \\&= \frac{59}{2} \end{aligned} \]
