Answer
$-4$
Work Step by Step
RECALL:
$\frac{a}{b}\div\frac{c}{d} =\frac{a}{b}\times\frac{d}{c} $
We use the rule above to obtan:
$(-\frac{2}{3})\times(\frac{3}{4})\times\frac{8}{1}$
Then, we multiply the numerators by each other and multiply the denominators by each other:
$-\frac{2\times3\times8}{3\times4\times1}$
Now, we cancel out the common factors in the numerator and the denominator to simplify the expression:
$-\frac{2\times3\times8}{3\times4\times1}=-\frac{2\times1\times8}{1\times4\times1}=-\frac{2\times1\times2}{1\times1\times1}=-4$
