Answer 1

$1) frac{2 - frac{1}{ frac{3}{4} } }{2 + frac{1}{ frac{3}{4} } } = frac{2 - frac{4}{3} }{2 + frac{4}{3} } = frac{ frac{2}{3} }{ frac{10}{3} } = frac{2}{10} = frac{1}{5} = 0.2 \ 2) frac{4 + frac{1}{ frac{1}{6} } }{4 - frac{1}{ frac{1}{6} } } = frac{4 + 6}{4 - 6} = frac{10}{ - 2} = - 5 \ 3)1 - frac{1}{ frac{3}{2} } = 1 - frac{2}{3} = frac{1}{3} = 0.3 \ 4)2 frac{2}{ frac{1}{3} } = 2 + 6 = 8 \ 5)1 + frac{1}{1 + frac{1}{ frac{3}{2} } } = 1 + frac{1}{1 + frac{2}{3} } = 1 + frac{1}{ frac{5}{3} } = 1 + frac{3}{5} = frac{8}{5} = 1 frac{3}{5} = 1.6 \ 6)3 - frac{3}{3 - frac{1}{ frac{2}{3} } } = 3 - frac{3}{3 - frac{3}{2} } = 3 - frac{3}{ frac{3}{2} } = 3 - 2 = 1$
