Answer 1

а)

$9 \frac{2}{\\ \\ 11} - (4 \frac{5}{11} + 2 \frac{6}{11} ) = \frac{101}{11} - ( \frac{49}{11} + \frac{28}{11} ) = \frac{101}{11} - 7 = \frac{24}{11}$

б)

$( \frac{5}{6} + 4 \frac{2}{6} ) - (3 \frac{2}{5} - \frac{2}{5} ) = ( \frac{5}{6} + \frac{26}{6} ) - ( \frac{17}{5} - \frac{2}{5} ) = \frac{31}{6} - ( \frac{17}{5} - \frac{2}{5} ) = \frac{31}{6} - 3 = \frac{13}{6}$
