Explicație pas cu pas:
= [tex][(-\frac{3}{5} )*\frac{25}{10} +\frac{5}{6} ] : \frac{10}{21} +\frac{11}{10} +\frac{1}{10} *9[/tex]
= [tex](-\frac{75}{50} +\frac{5}{6} )*\frac{21}{10} +\frac{11}{10} +\frac{9}{10}[/tex]
= [tex](-\frac{3}{2} +\frac{5}{6} )*\frac{21}{10} + \frac{20}{10}[/tex]
= [tex]\frac{-9+5}{6} * \frac{21}{10} + 2[/tex]
= [tex]\frac{-4}{6} * \frac{21}{10} +2[/tex]
= [tex]\frac{-42}{60} +2[/tex]
= [tex]\frac{-7}{10} + 2[/tex]
= [tex]\frac{-7}{10} + \frac{20}{10} = \frac{13}{10} = 1,3[/tex]
