Answer 2

Step-by-step explanation:

$\frac{5}{9} + ( \frac{ - 3}{11} ) + \frac{7}{9} +( \frac{ - 7}{11} ) \\ (rearrange \: fractions) \\ = \frac{5}{9} + \frac{7}{9} + ( \frac{ - 3}{11} ) + ( \frac{ - 7}{11} ) \\ = \frac{5 + 7}{9} + \frac{ - 3 + ( - 7)}{11} \\ = \frac{12}{9} + \frac{ - 3 - 7}{11} \\ = \frac{12 \div 3}{9 \div 3} + \frac{ - 10}{11} \\ = \frac{4}{3} + \frac{ - 10}{11} \\ (LCM \: of \: 3 \: and \: 11 \: is \: 33) \\ = \frac{(4 \times 11) + ( - 10 \times 3)}{ 33} \\ = \frac{44 + ( - 30)}{33} \\ = \frac{44 - 30}{33} \\ = \frac{14}{33}$

Hence the answer is 14/33.

hope it helps.
