DashaV19022001 1) |-7|-|-3,6|:|1,2| = -7 + 3,6 : 1,2 = -7 + 3 = - 4

2) |6/3,7|:|-9|+4/1,3 = $\frac{6}{3,7}$ : -9 + $\frac{4}{1,3}$ = $\frac{6}{3,7}$ : $\frac{-9}{1}$ + $\frac{4}{1,3}$ =   $\frac{6}{3,7}$ : $\frac{-11,7 + 4}{1,3}$ =   $\frac{6}{3,7}$ : $\frac{-7,7}{1,3}$ = $\frac{6}{3,7}$ ×   $\frac{1,3}{-7,7}$ = $\frac{7,8}{-28,49}$

3) |-7,24|*|-1/1,7|*3 = -7,24 × $\frac{-1}{1,7}$ × 3 = -21,72 × $\frac{-1}{1,7}$ =   $\frac{-2172}{1}$ ×   $\frac{-1}{1,7}$ = $\frac{2172}{1,7}$

4)|-2,7|:|-1/4,5|*|1/5,9| = -2,7 : $\frac{-1}{4,5}$ × $\frac{-1}{5,9}$ = $\frac{-2,7}{1}$ : $\frac{-1}{26,55}$ = $\frac{-2,7}{1}$   × $\frac{26,55}{-1}$ = $\frac{-71,685}{-1}$ = 71,685
