Question

Answer 1

=-3/5(-1/9-5/6+7/2)

=-3/5*(-2/18-15/18+63/18)

=-3/5*56/18

=-3/5*28/9

=-84/45

=-28/15

Answer 2

\(=\dfrac{-3}{5}.\left(\dfrac{-1}{9}+\dfrac{-5}{6}+\dfrac{7}{2}\right)\)

\(=\dfrac{-3}{5}.\left(\dfrac{-4}{36}+\dfrac{-30}{36}+\dfrac{126}{36}\right)\)

\(=\dfrac{-3}{5}.\dfrac{92}{36}\)

\(=\dfrac{-3}{5}.\dfrac{23}{9}\)

\(=-\dfrac{23}{15}\)
