\[ 810 - 90 + \frac{112254}{85} = \frac{173454}{85} = 2040.6\overline{3529411764705882} \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{810}{1}\), \(\frac{-90}{1}\), and \(\frac{112254}{85}\) is \(85\). \[ \begin{aligned} 810 - 90 + \frac{112254}{85} &= \frac{810 \cdot 85}{1 \cdot 85} + \frac{-90 \cdot 85}{1 \cdot 85} + \frac{112254 \cdot 1}{85 \cdot 1} \\ &= \frac{68850 + -7650 + 112254}{85} \\ &= \frac{173454}{85} \end{aligned} \]
