$( - \frac{15}{23} ) + ( - \frac{19}{23} ) =$

$= - \frac{15}{23} - \frac{19}{23}$

$= - \frac{34}{23}$

b/

$( \frac{3}{4} + \frac{5}{3} ) + ( - \frac{1}{5} ) =$

$= \frac{29}{12} - \frac{1}{5}$

$= \frac{133}{60}$

c/

$( - \frac{2}{5} + 4) - ( - \frac{1}{3} + 1) =$

$= \frac{18}{5} - \frac{2}{3}$

$= \frac{44}{15}$
