\[ 12 + 52.5 + 37.5 = 102 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{12}{1}\), \(\frac{52}{1}\), \(\frac{5}{10}\), \(\frac{37}{1}\), and \(\frac{5}{10}\) is \(10\). \[ \begin{aligned} 12 + 52.5 + 37.5 &= \frac{12 \cdot 10}{1 \cdot 10} + \frac{52 \cdot 10}{1 \cdot 10} + \frac{5 \cdot 1}{10 \cdot 1} + \frac{37 \cdot 10}{1 \cdot 10} + \frac{5 \cdot 1}{10 \cdot 1} \\ &= \frac{120 + 520 + 5 + 370 + 5}{10} \\ &= \frac{1020}{10} \\&= 102 \end{aligned} \]
