\[ 72.73 + 20 = \frac{9273}{100} = 92.73 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{72}{1}\), \(\frac{73}{100}\), and \(\frac{20}{1}\) is \(100\). \[ \begin{aligned} 72.73 + 20 &= \frac{72 \cdot 100}{1 \cdot 100} + \frac{73 \cdot 1}{100 \cdot 1} + \frac{20 \cdot 100}{1 \cdot 100} \\ &= \frac{7200 + 73 + 2000}{100} \\ &= \frac{9273}{100} \end{aligned} \]
