Question

\(-\frac{10}{11}\cdot\frac{8}{9}+\frac{7}{18}\cdot\frac{10}{11}\)

Answer 1

-10/11.8/9+7/18.10/11

=10/11.-8/9+7/18.10/11

=10/11.(-8/9+7/18)

=10/11.-1/2

=-5/11

Answer 2

\(-\frac{10}{11}\cdot\frac{8}{9}+\frac{7}{18}\cdot\frac{10}{11}\)

\(=\frac{10}{11}\cdot\frac{-8}{9}+\frac{7}{18}\cdot\frac{10}{11}\)

\(=\frac{10}{11}\cdot\left(-\frac{8}{9}+\frac{7}{18}\right)\)

\(=\frac{10}{11}\cdot\frac{-1}{2}\)

\(=-\frac{5}{11}\)
