a) [tex]\frac{6}{8}[/tex] + [tex]\frac{1}{4}[/tex] (amplificam cu 2) = [tex]\frac{6}{8}[/tex] + [tex]\frac{2}{8}[/tex] = [tex]\frac{10}{8}[/tex] (simplificam cu 2) = [tex]\frac{5}{4}[/tex]
b) [tex]\frac{12}{6}[/tex] ( amplificam cu 7) + [tex]\frac{1}{7}[/tex] (amplificam cu 6) = [tex]\frac{84}{42}[/tex] + [tex]\frac{6}{42}[/tex] = [tex]\frac{90}{42}[/tex] (simplificam cu 2)
= [tex]\frac{45}{21}[/tex] ( simplificam cu 3) = [tex]\frac{15}{7}[/tex]
c) [tex]\frac{3}{3}[/tex] (amplificam cu 13)- [tex]\frac{12}{13}[/tex] (amplificam cu 3) = [tex]\frac{39}{39}[/tex] + [tex]\frac{36}{39}[/tex] = [tex]\frac{75}{39}[/tex] (simplificam cu 3) = [tex]\frac{25}{13}[/tex]
d) [tex]\frac{4}{3}[/tex] (amplificam cu 11)- [tex]\frac{11}{11}[/tex] (amplificam cu 3) = [tex]\frac{44}{33} - \frac{33}{33}[/tex] = [tex]\frac{10}{33}[/tex]
Mult succes! Coronita? :)
