Answer
$-\frac{7}{8}$
Work Step by Step
First, we multiply the numerators by each other and the denominators by each other:
$\frac{3}{4}\times-\frac{14}{12}=-\frac{3\times14}{4\times12}=-\frac{42}{48}$
Next, we simplify the resultant expression to obtain the answer:
$-\frac{42}{48}=-\frac{21\times2}{24\times2}=-\frac{21}{24}=-\frac{7\times3}{8\times3}=-\frac{7}{8}$
