#### Answer

9$\frac{4}{63}$

#### Work Step by Step

We start by subtracting the whole numbers: $17-8=9$. In order to add or subtract fractions, we start by making a common denominator (bottom of the fraction). Thus, we multiply 2/7 by 9/9 and 2/9 by 7/7 to obtain: $\frac{18}{63}-$($\frac{14}{63}$)=$\frac{4}{63}$. We add the 9 to get an answer of 9$\frac{4}{63}$.
