​

Answer 1

Answer:

$⟹\frac{-8}{9} × \frac{-6}{7} - \frac {1}{10} × \frac {-3}{5}+\frac {3}{5} × \frac {-2}{7} - \frac {8}{9} × \frac {-5}{11}\\</p><p>\\</p><p>⟹( \frac {48}{63}) - ( \frac {-3}{50}) + (\frac {-6}{15}) - (\frac {-40}{99})\\</p><p>\\</p><p>⟹\frac {48}{63} + \frac {3}{50} - \frac {6}{15} + \frac {40}{99}\\</p><p>\\</p><p>⟹(\frac {2400 + 189}{3150}) ( \frac { - 198 + 200}{495})\\</p><p>\\</p><p>⟹\frac{2589}{3150} + \frac {2}{495}\\</p><p>\\</p><p>⟹\frac {863}{1056} + \frac {2}{495}\\</p><p>\\</p><p>⟹\frac {12945 + 64}{15840}\\</p><p>\\</p><p>⟹\frac {13009}{15840}\\</p><p>\\</p><p>⟹0.82 (approx.)$
