Addition of Fractions: Multiplication of signed numbers

$-3+(-\frac{1}{2})+(\frac{3}{8})+\frac{5}{8}=$

$-\frac{5}{2}$

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

$-\frac{3}{4}$

$-\frac{4}{9}+5+(-2)+\frac{5}{9}=$

$\frac{28}{9}$

$-5+-\frac{1}{2}+10+(-\frac{3}{4})=$

$\frac{15}{4}$

$-\frac{3}{8}-(-\frac{5}{8})-(-\frac{1}{2})=$

$\frac{3}{4}$

$-\frac{14}{7}+(-3)-\frac{1}{2}-(-\frac{1}{4})=$

$-\frac{21}{4}$

Solve:

$-\frac{4}{16}-(-\frac{3}{8})+\frac{2}{8}+(-\frac{1}{4})=$

$\frac{1}{8}$
