\[ 89.57 + 64 + 2.36 = \frac{15593}{100} = 155.93 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{89}{1}\), \(\frac{57}{100}\), \(\frac{64}{1}\), \(\frac{2}{1}\), and \(\frac{36}{100}\) is \(100\). \[ \begin{aligned} 89.57 + 64 + 2.36 &= \frac{89 \cdot 100}{1 \cdot 100} + \frac{57 \cdot 1}{100 \cdot 1} + \frac{64 \cdot 100}{1 \cdot 100} + \frac{2 \cdot 100}{1 \cdot 100} + \frac{36 \cdot 1}{100 \cdot 1} \\ &= \frac{8900 + 57 + 6400 + 200 + 36}{100} \\ &= \frac{15593}{100} \end{aligned} \]
