Answer 1

= (3/11 * 8/17 + 8/11 * 8/17)+(54 * 1 13/27 - 54 * 13/27)=8/17*(3/11+8/11)+
+54*(1 13/27 - 13/17)= 8/17 *1 + 54*1=54+8/17=54 8/17

Answer 2

$(\frac{3}{11} \cdot \frac{8}{17}+ \frac{8}{11} \cdot \frac{8}{17})+(54\cdot 1 \frac{13}{27}-54 \cdot \frac{13}{27})= \\ =\frac{8}{17}\cdot (\frac{3}{11}+ \frac{8}{11})+54\cdot (1 \frac{13}{27}-\frac{13}{27})= \\ =\frac{8}{17}\cdot \frac{3+8}{11}+54\cdot 1=\frac{8}{17}+54=54\frac{8}{17}$
