Answer 2

Step-by-step explanation:

5.(1)

$\frac{4}{5 } + \frac{11}{7} + \frac{ - 7}{5} + \frac{ - 2}{7}$

$= \frac{4}{5} + \frac{11}{7} - \frac{7}{5} - \frac{2}{7}$

$= \frac{28 + 55}{35} - \frac{49 - 10}{35}$

$= \frac{83}{35} - \frac{39}{35}$

$= \frac{83 - 39}{35}$

$= \frac{44}{35}$

5.(2)

$\frac{3}{7} + \frac{4}{9} + \frac{ - 5}{21} + \frac{2}{3}$

$= \frac{3}{7} + \frac{4}{9} - \frac{5}{21} + \frac{2}{3}$

$= \frac{27 + 28}{63} - \frac{5 + 14}{21}$

$= \frac{55}{63} - \frac{19}{21}$

$= \frac{55 - 57}{63}$

$= \frac{ - 2}{63}$
