2. a) [tex]\frac{12}{36} = \frac{6}{18} = \frac{2}{6} =\frac{1}{3}[/tex] simplificam cu 2, apoi cu 3 si 2
[tex]\frac{16}{56} =\frac{8}{28} =\frac{4}{14} =\frac{2}{7}[/tex] simplificam cu 2, 2 si 2
b) [tex]\frac{7}{11} =\frac{7*7}{11*7} = \frac{49}{77}[/tex]
[tex]\frac{11}{23} = \frac{11*7}{23*7} =\frac{77}{161}[/tex]
c) [tex]\frac{45}{19} =2\frac{7}{19}[/tex] [tex]\frac{59}{8} = 7\frac{3}{8}[/tex]
d) 2[tex]\frac{4}{13} = \frac{2*13+4}{13}[/tex]= [tex]\frac{30}{13}[/tex]
6[tex]\frac{5}{6} =\frac{6*6+5}{6} =\frac{41}{6}[/tex]
