Question

2/5 x -2/9 + 2/5 x 7/-9 + -1/5

Answer 1

`2 / 5 xx [-2] / 9 + 2 / 5 xx 7 / [-9] + [-1] / 5`

`= 2 / 5 xx ( [-2] / 9 + [-7] / 9 ) + [-1] / 5`

`= 2 / 5 xx [-9] / 9 + [-1] / 5`

`= [-2] / 5 + [-1] / 5`

`= [-3] / 5`

Answer 2

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

Answer 3

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