Ответ:

$\frac{8}{9}$-(4$\frac{2}{7}$-3$\frac{1}{7}$:1$\frac{1}{2}$)=$\frac{8}{9}$-(4$\frac{2}{7}$-$\frac{22}{7}$:$\frac{3}{2}$)=$\frac{8}{9}$-(4$\frac{2}{7}$-$\frac{22}{7}$*$\frac{2}{3}$)=$\frac{8}{9}$-(4$\frac{2}{7}$-$\frac{44}{21}$)=$\frac{8}{9}$-($\frac{30}{7}$-$\frac{44}{21}$)=$\frac{8}{9}$-($\frac{90}{21}$-$\frac{44}{21}$)=$\frac{8}{9}$-$\frac{46}{21}$=$\frac{56}{63}$-$\frac{138}{63}$=-$\frac{82}{63}$=-1$\frac{19}{63}$

Вроде так.
