Calcule. 8/7 X 14/16 / 9/7 : 18/21

Answer 1

boa noite !!!!

$\frac{8}{7} \times \frac{ \frac{14}{16} }{ \frac{9}{7} } \div \frac{18}{21} \\ \\ \frac{8}{7} \times \frac{49}{72} \times \frac{21}{18} \\ \\ \frac{7}{9} \times \frac{7}{6} \\ \\ = \frac{49}{54}$

espero que eu tenha conseguido te ajudar...
