Answer 1

Ответ:

$96) (\frac{13}{30} - \frac{11}{20}) . \frac{9}{5} = \frac{26 - 33}{60} . \frac{9}{5} = -\frac{7}{60} . \frac{9}{5} = -\frac{21}{100} = -0,21$

$97) (\frac{17}{15} - \frac{1}{12}) . \frac{20}{3} = \frac{68 - 5}{60} . \frac{20}{3} = \frac{63}{60} . \frac{20}{3} = \frac{21}{3} = 7$

$98) (\frac{5}{33} - \frac{8}{15}) . \frac{11}{5} = \frac{25 - 88}{165} . \frac{11}{5} = -\frac{63}{165} . \frac{11}{5} = -\frac{63}{15 . 5} = -\frac{21}{25} = -0,84$
