    $\frac{38}{45}$ - ($\frac{8}{45}$ - $\frac{17}{51}$ - $\frac{3}{11}$) 

= $\frac{38}{45}$ - $\frac{8}{45}$ + $\frac{17}{51}$ + $\frac{3}{11}$

= ($\frac{38}{45}$ - $\frac{8}{45}$)  + $\frac{17}{51}$ + $\frac{3}{11}$

= $\frac{2}{3}$ + $\frac{1}{3}$ + $\frac{3}{11}$

= $\frac{3}{3}$ + $\frac{3}{11}$

= 1 + $\frac{3}{11}$

= $\frac{14}{11}$
