Answer 2

\(\frac{-4}{11}.\frac{2}{5}+\frac{6}{11}.\frac{-3}{10}\)

=\(\frac{2}{11}.\left(-2\right).\frac{2}{5}+\frac{2}{11}.3.\frac{-3}{10}\)

=\(\frac{2}{11}.\frac{-4}{5}+\frac{2}{11}.\frac{-9}{10}\)

=\(\frac{2}{11}.\left(\frac{-4}{5}+\frac{-9}{10}\right)\)

=\(\frac{2}{11}.\frac{-17}{10}\)

=\(\frac{-17}{55}\)

Answer 3

-4/11 * 2/5 + 6/11 * -3/10

= -8/55 +  (-9/55)

= -17/55
