[ - 1,5 * (- 4 2/3)]/(- 3 : 2 1/2 + 5 1/5 + 6 ) =
= (15/10 * 14/3)/( - 3 : 5/2 + 5 1/5 + 6 ) = (5/5 * 7)/(- 3 * 2/5 + 5 1/5 + 6) =
= 7/(- 6/5 + 5 1/5 + 6) = 7/(- 1 1/5 + 11 1/5) = 7/10 = 0,7
[tex]\frac{-1,5\cdot(-4\frac{2}{3})}{-3:2\frac{1}{2}+5\frac{1}{5}+6} = \frac{-\frac{15}{10}\cdot(-\frac{4\cdot3+2}{3})}{-3:\frac{2\cdot2+1}{2}+\frac{5\cdot5+1}{5}+6}=\frac{-\frac{3}{2}\cdot(-\frac{14}{3})}{-3:\frac{5}{2}+\frac{26}{5}+6} = \frac{\frac{14}{2}}{-3\cdot\frac{2}{5}+\frac{26}{5}+6}} =\frac{7}{-\frac{6}{5}+\frac{26}{5} + 6}}=\\\\=\frac{7}{\frac{20}{5}+6} = \frac{7}{4+6} =\frac{7}{10} = 0,7[/tex]
