Answer
$-\frac{11}{40}$
Work Step by Step
$(\frac{3}{4}\div\frac{6}{5})-(\frac{3}{4}\times\frac{6}{5})$
$=(\frac{3}{4}\times\frac{5}{6})-(\frac{3}{4}\times\frac{6}{5})$
$=(\frac{1}{4}\times\frac{5}{2})-(\frac{3}{2}\times\frac{3}{5})$
$=\frac{5}{8}-\frac{9}{10}$
$=\frac{25}{40}-\frac{36}{40}$
$=-\frac{11}{40}$
