Answer 1

$a) \: - \frac{7}{6} + ( \frac{3}{8} \times ( - \frac{5}{9} )) - ( \frac{5}{3} \div ( - \frac{4}{7} )) \\ \frac{7}{6} + ( - \frac{5}{24} ) - ( \frac{5}{3} \times (- \frac{7}{4} )) \\ \frac{23}{24} - ( - \frac{35}{12} ) \\ \frac{23}{24} + \frac{35}{12} \\ \frac{31}{8} \\ 3.875$

$b) \: (( \frac{1}{6} - \frac{1}{5} ) \times (4 - \frac{9}{4} )) + (3 \times ( - \frac{1}{9} )) \\ \\ (( - \frac{1}{30} ) \times \frac{7}{4} ) + ( - \frac{1}{3} ) \\ - \frac{7}{120} - \frac{1}{3} \\ - \frac{47}{120}$
