c) [tex]\frac{1}{1}[/tex] x [tex]\frac{5}{16}[/tex] = [tex]\frac{5}{16}[/tex]
d) [tex]\frac{3}{3}[/tex] x [tex]\frac{11}{6}[/tex] = [tex]\frac{33}{18}[/tex]
e) [tex]\frac{1}{7}[/tex] x [tex]\frac{14}{5}[/tex] = [tex]\frac{14}{35}[/tex]
f) [tex]\frac{22}{7}[/tex] x [tex]\frac{21}{22}[/tex] se simplifica pe diagonala "22" si ne ramane = [tex]\frac{21}{7}[/tex] = 3
