Question

3/7.4/11+3/7.7/11-2

Answer 1

`3/7 .4/11+3/7 .7/11-2`

`= 3/7 . ( 4/11 + 7/11)-2`

`= 3/7 . 11/11 -2`

`=3/7 . 1-2`

`= 3/7-2`

`= 3/7 - 14/7`

`=-11/7`

Answer 2

`3/7*4/11+3/7*7/11-2`

`=3/7*(4/11+7/11)-2`

`=3/7*1-2`

`=3/7-2`

`=3/7-14/7`

`=-11/7`

Answer 3

= -11/7

Answer 4

\(\dfrac{3}{7}\times\dfrac{4}{11}+\dfrac{3}{7}\times\dfrac{7}{11}-2\\ =\dfrac{3}{7}\times\left(\dfrac{4}{11}+\dfrac{7}{11}-2\right)\\ =\dfrac{3}{7}\times1-2\\ =\dfrac{3}{7}-2\\ =\dfrac{3}{7}-\dfrac{14}{7}\\ =-\dfrac{11}{7}\)
