Answer 1

$c) (-2\sqrt{6} )*(\frac{1}{4}\sqrt{8} ):(\frac{3}{4}\sqrt{12} )=\\(-2\sqrt{6} )*(\frac{1\sqrt{8} }{4} ):(\frac{3\sqrt{12} }{4} )=\\\frac{(-2\sqrt{6} )*(1\sqrt{8}) }{4}: (\frac{3\sqrt{12} }{4} )=\\\frac{-2\sqrt{48} }{4}: (\frac{3\sqrt{12} }{4} )=\\\frac{-2\sqrt{48} }{4}*\frac{4}{3\sqrt{12} } =\\\frac{2\sqrt{48} }{3\sqrt{12} } =\\\frac{2*4\sqrt{3} }{3*2\sqrt{3} }=\\\frac{8\sqrt{3} }{6\sqrt{3} } =\frac{8}{6} =\frac{4}{3}$
