Respuesta:

A .- $\frac{12}{7}+ \frac{4}{7} +\frac{20}{7} = \frac{12 + 4 + 20}{7} = \frac{36}{7}$

B.- $\frac{21}{13}+ \frac{14}{13} +\frac{10}{13} = \frac{21 + 14 + 10 }{13} = \frac{45}{13}$

C.- $\frac{15}{11}+ \frac{10}{11} +\frac{21}{11} = \frac{15 + 10 + 21 }{11} = \frac{46}{11}$

E.- $\frac{23}{7} - \frac{14}{7} = \frac{23 - 14 }{7} =\frac{9}{7}$

F.-$\frac{43}{11} - \frac{29}{11} = \frac{43 - 29 }{11} = \frac{14}{11}$

G.-$\frac{89}{13} - \frac{78}{13} = \frac{89 - 78}{13} = \frac{11}{13}$
