Answer 2

Answer:

$( \frac{7}{9} \times \frac{ - 1}{2} ) + ( \frac{3}{5} \times \frac{4}{7} \times \frac{ - 3}{2}) \\ = ( \frac{7}{9} \times \frac{ - 1}{2} ) + ( \frac{3}{5} \times \frac{_{2 \: \: \: } \cancel 4}{7} \times \frac{ - 3}{ \cancel 2 _{ \: \: \: 1} }) \\ = \frac{ - 7}{18} + \frac{ - 18}{35} \\ = \frac{ - 245 + ( - 324)}{630} \\ = \frac{ - 245 - 324}{630} \\ = \underline{ \underline{ \frac{ - 569}{630} }}$
