Question

\(\dfrac{-5}{7}\)x\(\dfrac{2}{11}\)+\(\dfrac{-5}{7}\)x\(\dfrac{9}{11}\)+\(\dfrac{5}{7}\)

Answer 1

=5/7.-2/11+5/7.-9/11+5/7.1

=5/7.(-2/11+-9/11+1)
=5/7.0

=0

Answer 2

Answer 3

\(=\dfrac{5}{7}\times\left(\dfrac{-2}{11}+\dfrac{-9}{11}+1\right)=\dfrac{5}{7}\times\dfrac{0}{11}=0\)

Answer 4

`=-5/7×(2/11+9/11)+5/7`

`=-5/7×1+5/7`

`=-5/7+5/7`

`=0`
