2.9 . 3/-11 + 2/9 . -8/11 + 1/3
= 2/9 . (3/-11 + -8/11) + 1/3
= 2/9 . (-1) + 1/3
= -2/9 + 1/3
= 1/9
3/5 . 7/8 - 3/5 . -1/5
= 3/8 . (7/8 - 1/5)
= 3/8 . 43/40
= 129/320
\(\frac{2}{9}\) x \(\frac{3}{-11}\) +\(\frac{2}{9}\) x\(\frac{-8}{11}\) +\(\frac{1}{3}\) =\(\frac{1}{9}\) \(\frac{3}{5}\) *\(\frac{7}{8}\) -\(\frac{3}{5}\)*\(\frac{-1}{5}\) =\(\frac{129}{200}\)
