M = \(\dfrac{5}{7}.\dfrac{5}{11}+\dfrac{5}{7}.\dfrac{2}{11}-\dfrac{5}{7}.\dfrac{14}{11}\)

M = \(\dfrac{5}{7}.\left(\dfrac{5}{11}+\dfrac{2}{11}-\dfrac{14}{11}\right)\)

M = \(\dfrac{5}{7}.\dfrac{-7}{11}\)

M = \(\dfrac{-5}{11}\)

\(M=\dfrac{5}{7}.\dfrac{5}{11}+\dfrac{5}{7}.\dfrac{2}{11}-\dfrac{5}{7}.\dfrac{14}{11}\)

\(M=\dfrac{5}{7}.\left(\dfrac{5}{11}+\dfrac{2}{11}-\dfrac{14}{11}\right)\)

\(M=\dfrac{5}{7}.\dfrac{-7}{11}=-\dfrac{5}{11}\)

\(M=\dfrac{5}{7}\left(\dfrac{5}{11}+\dfrac{2}{11}-\dfrac{14}{11}\right)=\dfrac{5}{7}.\dfrac{-7}{11}=\dfrac{-5}{11}\)

M=\(\dfrac{5}{7}\) . \(\dfrac{5}{11}\) + \(\dfrac{5}{7}\) . \(\dfrac{2}{11}\) - \(\dfrac{5}{7}\) . \(\dfrac{14}{11}\)

=\(\dfrac{5}{7}\) . (\(\dfrac{5}{11}\) + \(\dfrac{2}{11}\) - \(\dfrac{14}{11}\))

=\(\dfrac{5}{7}\) . \(\dfrac{-7}{11}\)

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

\(M=\dfrac{5}{7}\left(\dfrac{5}{11}+\dfrac{2}{11}-\dfrac{14}{11}\right)\)

\(M=\dfrac{5}{7}.\dfrac{-7}{11}\)

\(M=\dfrac{-5}{11}\)
