Answer
a $-\frac{27}{8}$
b $\frac{1}{6}$
Work Step by Step
$x=-\frac{3}{4}$ and $y =\frac{9}{2} $
a $ xy=?$
Replace x and y with the above values
$-\frac{3}{4}\times\frac{9}{2}=-\frac{27}{8}$
b $x\div y=?$
Replace x and y with the above values
$-\frac{3}{4}\div\frac{9}{2}$
$-\frac{3}{4}\times\frac{2}{9}=\frac{1}{6}$
