Answer 1

а)
$frac{ frac{1}{2} }{ frac{3}{4} } = frac{1}{2} * frac{4}{3} = frac{2}{3}$
$frac{ frac{2}{3} }{ frac{1}{3} } = frac{2}{3} * frac{3}{1} = 2$
$frac{ frac{1}{4} }{ frac{3}{8} } = frac{1}{4} * frac{8}{3} = frac{2}{3}$

б)
$frac{1}{ frac{2}{3} } = 1 * frac{3}{2} = 1 frac{1}{2}$
$frac{1}{ frac{1}{7} } = 1 * 7 = 7$
$frac{1}{ frac{5}{2} } = 1 * frac{2}{5} = frac{2}{5}$

в)
$frac{ frac{8}{4} }{5} = frac{8}{4} * frac{1}{5} = frac{2}{1} * frac{1}{5} = frac{2}{5}$
$frac{ frac{2}{3} }{4} = frac{2}{3} * frac{1}{4} = frac{1}{6}$
$frac{ frac{2}{5} }{2} = frac{2}{5} * frac{1}{2} = frac{1}{5}$
