Answer 1

HOLA

Explicación paso a paso:

$\frac{2}{3} + \frac{5}{8} = \frac{16 + 15}{24} = \frac{31}{24}$

$\frac{5}{9} + \frac{3}{7} = \frac{35 + 27}{63} = \frac{62}{63}$

$\frac{7}{10} - \frac{4}{5} = \frac{35 - 40}{50} = - \frac{5}{50} = - \frac{1}{10}$

$\frac{9}{4 } - \frac{3}{2} = \frac{18 - 12}{8} = \frac{6}{8} = \frac{3}{4}$

$\frac{1}{6} + \frac{2}{15} = \frac{15 + 12}{90} = \frac{27}{90} = \frac{3}{10}$
