[tex](\frac{-45}{6} + \frac{3}{2} ) + (\frac{7}{12}-\frac{11}{4} ) = \\\frac{-45+9}{6} + \frac{7-33}{12} =\\\frac{-36}{6} + (\frac{-26}{12} ) = \\\frac{-36}{6} - \frac{13}{6} =\frac{-49}{6}[/tex]
Răspuns:
-4
Explicație pas cu pas:
[tex](-4\frac{5}{6} +\frac{3}{2}) +(\frac{7}{12}-1\frac{1}{4} )=(-\frac{29}{6} +\frac{3}{2} )+(\frac{7}{12}-\frac{5}{4} )=(-\frac{29}{6} +\frac{9}{6} )+(\frac{7}{12}-\frac{15}{12} )=-\frac{20}{6} -\frac{8}{12} =-\frac{10}{3} -\frac{2}{3} =-\frac{12}{3}=-4[/tex]
