\(\dfrac{-5}{7}\times\dfrac{2}{11}+\dfrac{-5}{7}\times\dfrac{9}{11}+1\\ =\dfrac{-5}{7}\times\left(\dfrac{2}{11}+\dfrac{9}{11}\right)+1\\ =\dfrac{-5}{7}\times1+1\\ =\dfrac{-5}{7}+1\\ =\dfrac{2}{7}\)
=-5/7(2/11+9/11)+1
=-5/7+1
=2/7
-5/7x2/11+-5/7x9/11+1
-5/7x(2/11+9/11)+1
-5/7x1+1
-5/7+1
2/7
\(\dfrac{-5}{7}.\dfrac{2}{11}+\dfrac{-5}{7}.\dfrac{9}{11}+1\)
\(\Rightarrow\dfrac{-5}{7}.\left(\dfrac{2}{11}+\dfrac{9}{11}\right)+1\\\Rightarrow-\dfrac{5}{7}+2\\ \Rightarrow-\dfrac{5}{7}+\dfrac{14}{7}\\ \Rightarrow\dfrac{9}{7}\)
