Answer:

\left(-\dfrac{4}{8}\right)\dfrac{3}{7}\times \dfrac{15}{16}\left(-\dfrac{14}{9}\right)=\dfrac{5}{16}\quad \left(\mathrm{Decimal:\quad }\:0.3125\right)

Step-by-step explanation:

\left(-\dfrac{4}{8}\right)\dfrac{3}{7}\times \dfrac{15}{16}\left(-\dfrac{14}{9}\right)

\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a

=\dfrac{4}{8}\times \dfrac{3}{7}\times \dfrac{15}{16}\times \dfrac{14}{9}

=\dfrac{1}{2}\times \dfrac{3}{7}\times \dfrac{14}{9}\times \dfrac{15}{16}

\mathrm{Multiply\:fractions}:\quad \dfrac{a}{b}\times \dfrac{c}{d}=\dfrac{a\:\times \:c}{b\:\times \:d}

=\dfrac{1\times \:3\times \:15\times \:14}{2\times \:7\times \:16\times \:9}

\mathrm{Multiply\:the\:numbers:}\:1\times \:3\times \:15\times \:14=630

=\dfrac{630}{2\times \:7\times \:16\times \:9}

\mathrm{Multiply\:the\:numbers:}\:2\times \:7\times \:16\times \:9=2016

=\dfrac{630}{2016}

\mathrm{Cancel\:the\:common\:factor:}\:126

=\dfrac{5}{16}
