Answer 1

1)
$frac{ frac{5}{6} - frac{1}{3} }{ frac{1}{3} - frac{5}{6} } = - frac{ frac{5}{6} - frac{1}{3} }{ frac{5}{6}- frac{1}{3} } = - 1$
2)
$frac{ frac{1}{2} - frac{2}{3} }{ frac{2}{3} - frac{1}{2} } = - frac{ frac{1}{2} - frac{2}{3} }{ frac{1}{2} - frac{2}{3} } = - 1$
3)
$frac{1.7 - 2}{2 - 1.7} = - frac{1.7 - 2}{1.7 - 2} = - 1$
4)
$frac{0.9 - 3}{3 - 0.9} = - frac{0.9 - 3}{0.9 - 3} = - 1$
