Answer 1

Resolução!

$\frac{5}{8} + \frac{7}{12} = = = = mmc = 24 \\ \\ \frac{15 + 14}{24} = \frac{29}{24} \\ \\ \\ = = = = = = = = = = = = = = = = = = = = = = = = = = = \\ \\ \\ \frac{7}{9} - \frac{1}{6} = = = = mmc = 18 \\ \\ \frac{14 - 3}{18} = \frac{11}{18} \\ \\ \\ = = = = = = = = = = = = = = = = = = = \\ \\ \\ \frac{4}{5} + \frac{1}{2} - \frac{5}{8} = = = mmc = 40 \\ \\ \frac{32 + 20 - 25}{40} = \frac{27}{40} \\ \\ \\ = = = = = = = = = = = = = = = = = = = \\ \\ \\ \frac{7}{15} + \frac{3}{15} - \frac{1}{10} = = = mmc = 30 \\ \\ \frac{14 + 6 - 3}{30} = \frac{17}{30} \\ \\ \\ \\ espero \: ter \: ajudado$
