Answer 1

$11 \frac{1}{11} \times 8 \frac{7}{9} + ( - 11 \frac{1}{11} ) \times 3 \frac{4}{9} - 11 \frac{1}{11} \times 3 \frac{1}{3} = 11 \frac{1}{11} \times (8 \frac{7}{9} - 3 \frac{4}{9} - 3 \frac{1}{3} ) = \frac{122}{11} \times ( \frac{79}{9} - \frac{31}{9} - \frac{10}{3} ) = \frac{122}{11} \times ( \frac{48}{9} - \frac{30}{9} ) = \frac{122}{11} \times \frac{18}{9} = \frac{122}{11} \times 2 = \frac{244}{11} = 22 \frac{2}{11}$
