Question

Answer 1

\(=\dfrac{-3}{5}+\dfrac{28}{5}\cdot\left(\dfrac{43}{56}+\dfrac{5}{24}-\dfrac{1}{3}\right)\)

\(=\dfrac{-3}{5}+\dfrac{28}{5}\cdot\dfrac{9}{14}=\dfrac{-3}{5}+\dfrac{18}{5}=\dfrac{15}{5}=3\)

Answer 2

`(-3/5) + 28/5 . (43/56 + 5/24 - 21/63)`

`=-3/5+28/5 . (43/56 + 5/24 - 1/3)`

`=-3/5+ 28/5 . (129/168 + 35/168 - 56/168)`

`=-3/5 + 28/5 . (( 129 + 35 - 56)/168)`

`=-3/5 + 28/5 . 9/14`

`=-3/5 + 18/5`

`=(-3+18)/5`

`=15/5`

`=3`
