1.- Calcula
[tex]a)\frac{3}{5} +\frac{1}{5} =\frac{3+1}{5} =\frac{4}{5}[/tex]
[tex]b)\frac{3}{7} +\frac{1}{7} =\frac{3+1}{7} =\frac{4}{7}[/tex]
[tex]c)\frac{1}{6} +\frac{2}{6} =\frac{1+2}{6} =\frac{3}{6}=\frac{1}{2}[/tex]
[tex]d)\frac{2}{10} +\frac{3}{10} +\frac{4}{10} =\frac{2+3+4}{10} =\frac{9}{10}[/tex]
2.- Calcula reduciendo primero a común denominador
[tex]a)\frac{5}{3}+ \frac{1}{6} =\frac{10+1}{6} =\frac{11}{6}[/tex]
[tex]b)\frac{7}{10}+ \frac{4}{15} =\frac{21+8}{30} =\frac{29}{30}[/tex]
[tex]c)\frac{1}{2}+ \frac{1}{3}+\frac{1}{6} =\frac{3+2+1}{6} =\frac{6}{6}=1[/tex]
3.- Opera y simplifica
[tex]a)1 +\frac{2}{5} =\frac{5+2}{5}= \frac{7}{5}[/tex]
[tex]b)\frac{3}{8} +1 =\frac{3+8}{8} =\frac{11}{8}[/tex]
[tex]c)\frac{2}{3} +5+\frac{3}{2} =\frac{4+30+9}{6} =\frac{43}{6}[/tex]
