Answer 1

Răspuns:

2. a) $\frac{12}{36} = \frac{6}{18} = \frac{2}{6} =\frac{1}{3}$   simplificam cu 2, apoi cu 3 si 2

$\frac{16}{56} =\frac{8}{28} =\frac{4}{14} =\frac{2}{7}$  simplificam cu 2, 2 si 2

b) $\frac{7}{11} =\frac{7*7}{11*7} = \frac{49}{77}$

$\frac{11}{23} = \frac{11*7}{23*7} =\frac{77}{161}$

c) $\frac{45}{19} =2\frac{7}{19}$            $\frac{59}{8} = 7\frac{3}{8}$

d) 2$\frac{4}{13} = \frac{2*13+4}{13}$= $\frac{30}{13}$

6$\frac{5}{6} =\frac{6*6+5}{6} =\frac{41}{6}$
