\[ .825075 - 1 = - \frac{6997}{40000} = -0.174925 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{825075}{1000000}\) and \(\frac{-1}{1}\) is \(1000000\). \[ \begin{aligned} .825075 - 1 &= \frac{825075 \cdot 1}{1000000 \cdot 1} + \frac{-1 \cdot 1000000}{1 \cdot 1000000} \\ &= \frac{825075 + -1000000}{1000000} \\ &= \frac{-174925}{1000000} \\&= - \frac{6997}{40000} \end{aligned} \]
