Answer 2

Step-by-step explanation:

$\scriptsize \frac{ - 22}{7} \div ( \frac{9}{14} - \frac{5}{21} ) = ( \frac{ - 22}{7} \div \frac{9}{14} ) - ( \frac{ - 22}{7} \div \frac{5}{21} )$

$\scriptsize \frac{ - 22}{7} \div ( \frac{189 - 70}{ 294} ) = ( \frac{ - 22}{ \cancel7} \times \frac{ \cancel{14}}{9} ) - ( \frac{ - 22}{7} \times \frac{21}{5} )$

$\scriptsize \frac{ - 22}{7} \div ( \frac{119}{294} ) = ( \frac{ - 44}{9} ) - ( \frac{462}{35} )$

$\scriptsize \frac{ - 22}{7} \times \frac{294}{119} = \frac{ - 44}{9} - \frac{462}{35}$

$\frac{ - 6468}{833} = \frac{1540 - 4158}{315}$

$\frac{ - 6468}{833} ≠ \frac{ - 2618}{315}$

$(a) \: \: ( \frac{ - 4}{1} \times \frac{7}{3} ) - ( - 4) \times \frac{9}{10}$

$( \frac{ - 28}{3} ) + \frac{ \cancel{36}}{ \cancel{10}}$

$\frac{ - 28}{3} + \frac{18}{ {5}}$

$\frac{ - 140 + 54}{15}$

$\frac{ - 86}{15}$

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

$( \frac{ - 20 + 18}{15} ) \times \frac{7}{9}$

$\frac{ - 2}{15} \times \frac{7}{9}$

$\frac{ - 14}{135}$

$(d) \: \: \frac{5}{2} \times ( \frac{ - 13}{4} - \frac{7}{6} )$

$\frac{5}{2} \times ( \frac{ - 39 - 14}{12} )$

$\frac{5}{2} \times ( \frac{ - 53}{12} )$

$\frac{ - 265}{24}$

$(e) \: \: ( \frac{ - 6}{5} + \frac{3}{2} ) \times ( - 3)$

$( \frac{ - 12 + 15}{10} ) \times ( - 3)$

$( \frac{ - 3}{10} ) \times ( - 3)$

$\frac{9}{10}$

I hope it is helpful
