$\frac{2}{3} + \frac{ - 11}{8} + \frac{ - 17}{3} + \frac{3}{8}$

$= \frac{16}{24} + \frac{ - 33}{24} + \frac{ - 136}{24} + \frac{9}{24}$

$= \frac{ - 147}{24}$

$= \frac{ - 4 9}{8}$

And,

$\frac{7}{8} + \frac{3}{10} + \frac{ - 5}{8} + \frac{ - 7}{20}$

$= \frac{35}{40} + \frac{12}{40} + \frac{ - 25}{40} + \frac{ - 14}{40}$

$= \frac{8}{40}$

$= \frac{1}{5}$
