Answer 2

Step-by-step explanation:

$5).Find : \\ a) . \frac{ - 3}{ - 11} + \frac{5}{9} \\ = \frac{ - 27 - 55}{ - 99} \\ = \frac{ - 82}{ - 99} \\ = \frac{82}{99} \\ b). \frac{ - 2}{3} + \frac{4}{5} \\ = \frac{ - 10 + 12}{15} \\ = \frac{2}{15} \\ c). \frac{ - 6}{13 } - \frac{ - 7}{15} \\ = \frac{ - 90 - ( - 91)}{175} \\ = \frac{ - 90 + 91}{175} \\ = \frac{1}{175} \\ d).\frac{ - 7}{12} \div \frac{ - 2}{ 13} \\ = \frac{ - 7}{12} \times \frac{ - 13}{ 2} \\ = \frac{ 91 }{24} \\ = 3 \frac{19}{24} \\ e).\frac{9}{2} \times \frac{ - 7}{4} \\ = \frac{ - 63}{8} \\ = 7 \frac{ - 7}{8}$
