$\frac{-\frac{3}{4}}{-\frac{9}{16}}$=$\frac{\frac{3}{4}}{\frac{9}{16}}$ Cancel the Minus Sign
=$\frac{3}{4}\times\frac{16}{9}$ Extract the denominator
=$\frac{1}{1}\times\frac{4}{3}$ Simplify the terms by cancelling common multiples, Divide 3 and 9 by 3 to obtain 1 and 3 respectively, Divide 4 and 16 by 4 to obtain 1 and 4 respectively
=$\frac{4}{3}$ Answer Obtained!
