Answer 1

$- \frac{2}{11} - \frac{9}{11} = \frac{-2-9}{11} = -\frac{11}{11} = -1$

$\frac{17}{5} -\frac{19}{5} = \frac{17-19}{5} = \frac{-2}{5}$

$- \frac{4}{6}+ \frac{7}{8}= \frac{-32+42}{48} = \frac{10}{48} = \frac{5}{24}$

$-\frac{5}{8} -\frac{11}{20} = \frac{-100-88}{160} = \frac{-188}{100} = \frac{-94}{50} = \frac{-47}{25}$

$\frac{9}{15} - \frac{-7}{12} = \frac{108+105}{180} = \frac{213}{180}$

[tex]( \frac{7}{5})(-\frac{8}{6}) = -\frac{56}{30} = {28}{15}
