Answer 1

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