Answer 1

Step-by-step explanation:

4)

$\frac{9}{5} + \frac{19}{3} + ( \frac{ - 9}{25} ) + ( \frac{ - 4}{3} ) + 1 \\ = \frac{9}{5} + \frac{19}{5} - \frac{9}{25} - \frac{4}{3} + 1 \\ = \frac{135 + 285 - 27 - 100 + 75}{75} \\ = \frac{368}{75} = 4 \frac{68}{75}$

$( \frac{2}{11} \times \frac{ - 22}{15} ) + ( \frac{ - 1}{6} \times \frac{3}{4} ) + ( \frac{ - 1}{21} \times \frac{ - 3}{5} ) \\ = - \frac{4}{15} - \frac{1}{8} + \frac{1}{35} \\ = \frac{ - 224 - 105 + 24}{840} \\ = - \frac{305}{840} = - \frac{61}{168}$
