Answer 1

$\frac{3}{1-\frac{1}{2} } =\frac{3}{\frac{1}{2} } =6\\\\\frac{1-\frac{1}{4} }{1\frac{1}{2} } =\frac{\frac{3}{4} }{\frac{3}{2} }=\frac{1}{2} \\\\\frac{\frac{2}{3}+\frac{1}{4} }{1\frac{5}{6} } =\frac{\frac{11}{12} }{\frac{11}{6} }=\frac{1}{2} \\\\\frac{8\frac{1}{3} }{\frac{8}{9} -\frac{1}{3} } =\frac{\frac{25}{3} }{\frac{5}{9} } =15$
