( a ) $( \frac{7}{5} \times \frac{ (- 3)}{12} ) + ( \frac{7}{5} \times \frac{5}{12})$

$= \frac{7}{5} ( \frac{( - 3)}{12} + \frac{5}{12})$

$= \frac{7}{5} ( \frac{ - 3 \: + \: 5}{12})$

$= \frac{7}{5} \times \frac{2}{12}$

$= \frac{14}{60}$

$= \frac{7}{30}$

( b ) $( \frac{9}{16} \times \frac{4}{12}) + ( \frac{9}{16} \times \frac{( - 3)}{9})$

$= \frac{9}{16}( \frac{4}{12} + \frac{( - 3)}{9})$

$= \frac{9}{16}( \frac{12 \: + \: ( - 12)}{36})$

$= \frac{9}{16}( \frac{12 \: - \: 12}{36})$

$= \frac{9}{16} \times \frac{0}{36}$

$= \frac{0}{16}$
