Answer 1

$(\frac{1}{4} -\frac{5}{6} ):\frac{5}{12} +|0,75-\frac{3}{2} |-\frac{1}{17} *(0,(6)+\frac{3}{4} )-\frac{34}{17} :30= \\ =-\frac{7}{12}*\frac{12}{5}+|\frac{3}{4}-\frac{3}{2}|-\frac{1}{17}*\frac{17}{2}-2*\frac{1}{30}= \\ =-\frac{7}{5}+|-\frac{3}{4}|-\frac{1}{12}-\frac{1}{15}=\bold{-\frac{4}{5}}$
