Answer 1

Explicación paso a paso:

$a) \frac{7}{9} + \frac{4}{8} = \frac{56 + 36}{72} = \frac{92}{72} = \frac{23}{18}$

$b) \frac{3}{4} + \frac{5}{6} + \frac{2}{5} = \frac{45 + 50 + 24}{60} = \frac{119}{60}$

$c) \frac{1}{3} + \frac{4}{2} + \frac{8}{7} = \frac{7 + 42 + 24}{21} = \frac{73}{21}$

$d) \frac{5}{4} + \frac{2}{3} + \frac{1}{6} = \frac{15 + 8 + 2}{12} = \frac{25}{12}$
