Hola!

Respuesta:

Las sumas son las:

A, B, C, D, E

Las restas son las:

F, G, H, I, J

Explicación paso a paso:

A)

[tex] \frac{4}{3} + \frac{2}{7} = \frac{28 + 6}{21} = \frac{34}{21} [/tex]

B)

[tex] \frac{3}{4} + \frac{5}{9} = \frac{27 + 20}{36} = \frac{47}{36} [/tex]

C)

[tex] \frac{2}{9} + \frac{2}{6} = \frac{2}{9} + \frac{1}{3} = \frac{5}{9} [/tex]

D)

[tex] \frac{6}{7} + \frac{3}{4} = \frac{24 + 21}{28} = \frac{45}{28} [/tex]

E)

[tex] \frac{8}{9} + \frac{4}{4} = \frac{8 + 9}{9} = \frac{17}{9} [/tex]

F)

[tex] \frac{4}{5} - \frac{5}{8} = \frac{32 - 25}{40} = \frac{7}{40} [/tex]

G)

[tex] \frac{7}{8} - \frac{2}{3} = \frac{21 - 16}{24} = \frac{5}{24} [/tex]

H)

[tex] \frac{4}{5} - \frac{4}{7} = \frac{28 - 20}{35} = \frac{8}{35} [/tex]

I)

[tex] \frac{2}{3} - \frac{6}{9} = \frac{2 - 2}{3} = 0[/tex]

J)

[tex] \frac{6}{7} - \frac{4}{5} = \frac{30 - 28}{35} = \frac{2}{35} [/tex]
