Question

Answer 1

\(=\dfrac{-3}{5}\left(\dfrac{5}{7}+\dfrac{3}{7}+\dfrac{6}{7}\right)=\dfrac{-3}{5}\cdot2=-\dfrac{6}{5}\)

Answer 2

\(\dfrac{-3}{5}.\dfrac{5}{7}+\dfrac{-3}{5}.\dfrac{3}{7}+\dfrac{-3}{5}.\dfrac{6}{7}=\dfrac{-3}{5}.\left(\dfrac{5}{7}+\dfrac{3}{7}+\dfrac{6}{7}\right)=\dfrac{-3}{5}.2=\dfrac{-6}{5}\)

Answer 3

\(=\dfrac{-3}{5}\left(\dfrac{5}{7}+\dfrac{3}{7}+\dfrac{6}{7}\right)\\ =-\dfrac{3}{5}.2\\ =-\dfrac{6}{5}\)

Answer 4

\(\dfrac{-3}{5}.\dfrac{5}{7}+\dfrac{-3}{5}.\dfrac{3}{7}+\dfrac{-3}{5}.\dfrac{6}{7}\)

\(=\dfrac{-3}{5}.\left(\dfrac{5}{7}+\dfrac{3}{7}+\dfrac{6}{7}\right)\)

\(=\dfrac{-3}{5}.\dfrac{14}{7}\)

\(=\dfrac{-3}{5}.2\)

\(=\dfrac{-6}{5}\)

Answer 5

-3/5.5/7+-3/5.3/7+-3/5.6/7

=-3/5.(5/7+3/7+6/7)

=-3/5.2=-6/5

Answer 6

=-3/7.(5/7+3/7+6/7)

=-3/7.2

=-6/7
