\[ \frac{3}{4} + 1\frac{1}{2} = \frac{9}{4} = 2.25 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{4}\), \(\frac{1}{1}\), and \(\frac{1}{2}\) is \(4\). \[ \begin{aligned} \frac{3}{4} + 1\frac{1}{2} &= \frac{3 \cdot 1}{4 \cdot 1} + \frac{1 \cdot 4}{1 \cdot 4} + \frac{1 \cdot 2}{2 \cdot 2} \\ &= \frac{3 + 4 + 2}{4} \\ &= \frac{9}{4} \end{aligned} \]
