Verified answer

A)

[tex]\frac{1}{3} +\frac{1}{2} +\frac{1}{5} \\MCM=30\\\frac{10+15+6}{30}= \frac{31}{30}[/tex]

B)

[tex]\frac{2}{5} +\frac{2}{7} -\frac{10}{35} \\\\\frac{10}{35} =\frac{2}{7} \\\\\frac{2}{5} +\frac{2}{7} -\frac{2}{7} \\\\[/tex]simplemente t quedará [tex]\frac{2}{5}[/tex]

E)[tex]\frac{3}{5} -\frac{2}{8}[/tex]   MCM=40

[tex]\frac{24-10}{40} =\frac{14}{40} =\frac{7}{20}[/tex]

E) [tex]\frac{7}{9} -\frac{4}{3}[/tex]   MCM= 9

[tex]\frac{7-12}{9} =-\frac{5}{9}[/tex]
