Answer 2

Solution

$( \frac{ - 14}{9} ) \times \frac{3}{5} \times (\frac{ - 4}{7} ) \times \frac{15}{16}$

Remove all the brackets

$= > \frac{-14}{9} \times \frac{3}{5} \times \frac{ - 4}{7} \times \frac{15}{16}$

$= > \frac{-14 \times 3}{9 \times 5} \times \frac{ - 4 \times 15}{7 \times 16} \\ \\ according \: to \: the \: property \: \\ whenever \: negative \: and \: positive \: \\ is \: being \: multiplied \: then \: the \: \\ answer \: comes \: in \: negative$

$\dfrac{\cancel{-42}}{\cancel{45}}$ \times$\dfrac{\cancel{-60}}{\cancel{112}}$

$= > \frac{14}{15} \times \frac{-15}{28}$

$\dfrac{\cancel{-14}}{\cancel{15}}$X $\dfrac{\cancel{-15}}{\cancel{28}}$

$= > \frac{-1}{1} \times \frac{-1}{2}$

$= > \frac{1}{2}$ answer
