Answer 1

$( \frac{3}{4} - \frac{1}{12} : \frac{1}{4}) - ( \frac{4}{3} - \frac{1}{2}) = \frac{3}{4} - \frac{1}{12} \times 4 - ( \frac{4}{3} - \frac{1}{2}) = \frac{3}{4} - \frac{1}{12} \times 4 - \frac{5}{6} = \frac{3}{4} - \frac{4}{12} - \frac{5}{6} = \frac{3}{4} - \frac{1}{3} - \frac{5}{6} = - \frac{5}{12}$
