Answer 1

$(\frac{5}{6} - 2 \frac{4}{11})*3.3 = (\frac{5}{6} - \frac{26}{11}) * \frac{33}{10} = \frac{-101}{66}* \frac{33}{10} = -\frac{101}{20}=-5.05$

Answer 2

$( \frac{5}{6} - 2 \frac{4}{11} ) \times 3.3 = ( \frac{5}{6} - \frac{26}{11} ) \times 3.3 = \\ = \frac{5 \times 11 -26 \times 6 }{6 \times 11} \times \frac{33}{10} = \frac{(55 - 156) \times 33}{2 \times 33 \times 10} = \\ = - \frac{101}{20} = - 5 \frac{1}{20} = - 5.05$
