ayudaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Answer 1

$\frac{4}{3} + \frac{2}{7} = \frac{28 + 6}{21} = \frac{34}{21}$

$\frac{3}{4} + \frac{5}{9} = \frac{27 + 20}{36} = \frac{47}{36}$

$\frac{2}{9} + \frac{2}{6} = \frac{18 + 12}{54} = \frac{30}{54} =se \: simplifica \: \frac{15}{27}$

$\frac{6}{7} + \frac{3}{4} = \frac{24 + 21}{28} = \frac{45}{28}$

$\frac{8}{5} + \frac{4}{4} = \frac{32 + 20}{20} = \frac{52}{20} = \frac{26}{10}simplificado$
