Salut!

a) $\frac{1}{5} * \frac{1}{4} = \frac{1*1}{5*4} = \frac{1}{20}$

b) $\frac{3}{7} * \frac{2}{11} = \frac{3*2}{7*11} = \frac{6}{77}$

c) $\frac{3}{8} * \frac{5}{6} = \frac{3*5}{8*6} = \frac{15}{48}$

d) $\frac{5}{9} * \frac{3}{4} = \frac{5*3}{9*4} = \frac{15}{36}$

e) $\frac{7}{15} * \frac{5}{14} = \frac{7*5}{15*14} = \frac{35}{210}$

f) $\frac{5}{6} * \frac{3}{?} = \frac{5*3}{6*?} = \frac{15}{6*?}$, unde "?" este numarul care nu se vede.

Succes!
