\(=\dfrac{-5}{7}.\left(\dfrac{2}{11}+\dfrac{9}{11}\right)+1\)
\(=\dfrac{-5}{7}.1+1\)
\(=\dfrac{-5}{7}+1=\dfrac{2}{7}\)
\(=\dfrac{-5}{7}.\left(\dfrac{2}{11}+\dfrac{9}{11}\right)+1\)
\(=\dfrac{-5}{7}.1+1\)
\(=\dfrac{-5}{7}+1\)
\(=\dfrac{-5}{7}+\dfrac{7}{7}=\dfrac{2}{7}\)
- 5/7 . 2/11 + - 5/7 . 9/11 + 1
=> - 5/7 . (2/11 + 9/11) + 1
=> - 5/7 + 1
=> 2/7
\(\dfrac{-5}{7}.\dfrac{2}{11}+\dfrac{-5}{7}.\dfrac{9}{11}+1=\dfrac{-5}{7}\left(\dfrac{2}{11}+\dfrac{9}{11}\right)+1\)
\(=\dfrac{-5}{7}.1+1\)
\(=\dfrac{-5}{7}+1\)
\(=\dfrac{2}{7}\)
