\[ 1.23 + 4.25 = \frac{137}{25} = 5.48 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{1}{1}\), \(\frac{23}{100}\), \(\frac{4}{1}\), and \(\frac{25}{100}\) is \(100\). \[ \begin{aligned} 1.23 + 4.25 &= \frac{1 \cdot 100}{1 \cdot 100} + \frac{23 \cdot 1}{100 \cdot 1} + \frac{4 \cdot 100}{1 \cdot 100} + \frac{25 \cdot 1}{100 \cdot 1} \\ &= \frac{100 + 23 + 400 + 25}{100} \\ &= \frac{548}{100} \\&= \frac{137}{25} \end{aligned} \]
