\[ 68 + \frac{1}{2} = \frac{137}{2} = 68.5 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{68}{1}\) and \(\frac{1}{2}\) is \(2\). \[ \begin{aligned} 68 + \frac{1}{2} &= \frac{68 \cdot 2}{1 \cdot 2} + \frac{1 \cdot 1}{2 \cdot 1} \\ &= \frac{136 + 1}{2} \\ &= \frac{137}{2} \end{aligned} \]
