RESOLVER:

a) [tex]\frac{7}{6}+\frac{2}{5}[/tex]

MCM de 6, 5 es 30, ahora reescribimos las fracciones basándonos en el mínimo común denominador

[tex]=\frac{35}{30}+\frac{12}{30}\\\\=\frac{35+12}{30}\\\\\boxed{=\frac{47}{30}}[/tex]

b) [tex]\frac{1}{2}+\frac{2}{5}\\[/tex]

MCM de 2, 5 es 10

[tex]=\frac{5}{10}+\frac{4}{10}\\\\=\frac{5+4}{10}\\\\\boxed{=\frac{9}{10}}[/tex]

c) [tex]\frac{3}{4}+\frac{1}{6}[/tex]

MCM de 4, 6 es 12

[tex]=\frac{9}{12}+\frac{2}{12}\\\\=\frac{9+2}{12}\\\\\boxed{=\frac{11}{12}}[/tex]

d) [tex]\frac{7}{5}-\frac{1}{3}[/tex]

MCM de 5, 3 es 15

[tex]=\frac{21}{15}-\frac{5}{15}\\\\=\frac{21-5}{15}\\\\\boxed{=\frac{16}{15}}[/tex]

e) [tex]\frac{5}{6}-\frac{2}{3}[/tex]

MCM de 6, 3 es 6

[tex]=\frac{5}{6}-\frac{4}{6}\\\\=\frac{5-4}{6}\\\\\boxed{=\frac{1}{6}}[/tex]
