Answer 2

Answer:

$1. \: \: ans = \frac{ - 3}{5} \\ 2. \: \: ans = \frac{ - 1}{2}$

Step-by-step explanation:

$1. \: \: \frac{ - 1}{2} + \frac{3}{5} + ( \frac{ - 7}{10} ) \\ = \frac{ - 1}{2} + \frac{3}{5} - \frac{7}{10} \\ = \frac{ - 5 + 6 - 7}{10} \\ = \frac{ - 6}{10} \\ \\ 2. \: \: \: \frac{ - 3}{4} + \frac{7}{8} + ( \frac{ - 9}{16} ) \\ = \frac{ - 3}{4} + \frac{7}{8} - \frac{9}{16} \\ = \frac{ - 13 + 14 - 9}{16} = \frac{ - 8}{16} = \frac{ - 1}{2}$
