Answer 1

Explicación paso a paso:

$\frac{4}{7} + \frac{3}{5} = \frac{20 + 21}{35} = \frac{41}{35}$

$\frac{6}{5} + \frac{4}{5} = \frac{11}{5} \\ \\ \frac{5}{7} + \frac{2}{9} = \frac{45 + 14}{63} = \frac{59}{63}$

$\frac{3}{8} + \frac{5}{7} = \frac{21 + 40}{56} = \frac{61}{56} \\ \\ \frac{2}{5} + \frac{4}{9} = \frac{18 + 20}{45} = \frac{38}{45} \\ \\ \frac{12}{17} + \frac{4}{5} = \frac{60 + 68}{85} = \frac{128}{85} \\ \\ \frac{13}{5} + \frac{9}{4} = \frac{52 + 45}{20} = \frac{97}{20}$

$\frac{4}{9} + \frac{8}{3} = \frac{12 + 72}{27} = \frac{84}{27} = \frac{28}{9} \\ \\ \frac{9}{11} + \frac{6}{7} = \frac{63 + 66}{77} = \frac{129}{77}$

$\frac{7}{10} + \frac{9}{10} = \frac{16}{10} = \frac{8}{5} \\ \\ \frac{14}{5} + \frac{2}{3} = \frac{42 + 10}{15} = \frac{52}{15}$
