\[ 150 + 200 + 12.50 = \frac{725}{2} = 362.5 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{150}{1}\), \(\frac{200}{1}\), \(\frac{12}{1}\), and \(\frac{5}{10}\) is \(10\). \[ \begin{aligned} 150 + 200 + 12.50 &= \frac{150 \cdot 10}{1 \cdot 10} + \frac{200 \cdot 10}{1 \cdot 10} + \frac{12 \cdot 10}{1 \cdot 10} + \frac{5 \cdot 1}{10 \cdot 1} \\ &= \frac{1500 + 2000 + 120 + 5}{10} \\ &= \frac{3625}{10} \\&= \frac{725}{2} \end{aligned} \]
