Answer 2

Answer:

$1) \: \frac{ - 9}{10} + \frac{22}{15} \\ = \frac{15( - 9) + 22(10)}{10 \times 15} \\ = \frac{ - 135 + 220}{150} \\ = \frac{85}{150} \\ = \frac{17}{30} \\ \\ \\ 2) \: \frac{ - 3}{8} - \frac{7}{11} \\ \\ = \frac{11( - 3) - 8(7)}{11 \times 8} \\ \\ = \frac{ - 33 - 56}{88} \\ \\ = \frac{ - 89}{88} \\ \\ \\ 3) \: \frac{ - 6}{5} \times \frac{9}{11} \\ \\ = \frac{ - 6 \times 9}{5 \times 11} \\ \\ = \frac{ - 54}{55} \\ \\ \\ 4) \: \frac{3}{13} \div ( \frac{ - 4}{65} ) \\ \\ = \frac{3}{13} \times \frac{ - 65}{ \: 4} \\ \\ = \frac{3}{13} \times \frac{13 \times - 5}{4} \\ \\ = 3 \times \frac{ - 5}{4} \\ \\ = \frac{ - 15}{4}$
