Answer 2

Explicación paso a paso:

$a) \\ ( - \frac{10}{9} + \frac{2}{7} ) \times ( - \frac{3}{2} ) = \\ \\ (\frac{ - 70 + 18}{63} ) \times ( - \frac{3}{2} )= \\ \\ - \frac{52}{63} \times ( - \frac{3}{2} ) = \frac{156}{126} = \frac{26}{21} \\ \\ b) \\ ( - \frac{5}{4} - \frac{11}{3} ) \div ( - \frac{1}{2} + \frac{1}{4} ) = \\ \\ ( \frac{ - 15 - 44}{12} ) \div ( \frac{ - 2 + 1}{4} )= \\ \\ ( - \frac{59}{12} )\div ( - \frac{1}{4} ) = \frac{236}{12} = \frac{59}{3} \\ \\ c) \\ ( \frac{25}{4} - \frac{30}{7} ) \div ( \frac{1}{7} \times \frac{3}{4} ) = \\ \\ ( \frac{175 - 120}{28} ) \div ( \frac{3}{28}) = \\ \\ \frac{55}{28} \div \frac{3}{28} = \frac{1540}{84} = \frac{55}{3}$
