Answer 1

Answer:

$m(n + p) = mn + mp \\ \frac{ - 3}{5} ( \frac{ - 2}{5} + \frac{ - 7}{5} ) = \frac{ - 3}{5} \times \frac{ - 2}{5} + \frac{ - 3}{5} \times \frac{ - 7}{5} \\ \frac{ - 3}{5} \times \frac{ - 9}{5} = \frac{6}{5} + \frac{21}{5} \\ \frac{27}{5} = \frac{27}{5} \\ lhs = rhs \\ \frac{ - 5}{12} ( \frac{7}{8} + \frac{ - 12}{3} ) = \frac{ - 5}{12} \times \frac{7}{8} + \frac{ - 5}{12} \times \frac{ - 12}{3} \\ \frac{ - 5}{12} \times \frac{ - 25}{8} = \frac{ - 35}{96} + \frac{5}{3} \\ \frac{125}{96} = \frac{125}{96} \\ lhs = rhs$
