\[ 0.75 + 2.5 = \frac{13}{4} = 3.25 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{75}{100}\), \(\frac{2}{1}\), and \(\frac{5}{10}\) is \(100\). \[ \begin{aligned} 0.75 + 2.5 &= \frac{75 \cdot 1}{100 \cdot 1} + \frac{2 \cdot 100}{1 \cdot 100} + \frac{5 \cdot 10}{10 \cdot 10} \\ &= \frac{75 + 200 + 50}{100} \\ &= \frac{325}{100} \\&= \frac{13}{4} \end{aligned} \]
