Answer
$\frac{11}{36}$
Work Step by Step
$\frac{3}{4}$ - $\frac{1}{2}$$\times$ $\frac{8}{9}$=
=$\frac{3}{4}$ - $\frac{1\times8}{2\times9}$=
=$\frac{3}{4}$ -$\frac{1\times2\times4}{2\times9}$=
=$\frac{3}{4}$ - $\frac{4}{9}$=
=$\frac{3}{4}$$\times$ $\frac{9}{9}$ - $\frac{4}{9}$$\times$$\frac{4}{4}$=
=$\frac{27}{36}$ - $\frac{16}{36}$=$\frac{27-16}{36}$ =
=$\frac{11}{36}$
