COM CÁLCULO POR FAVOR

Answer 1

Resposta:

a)

$\frac{ \frac{9}{2} }{ \frac{7}{3} } = \frac{9}{2} . \frac{3}{7} = \frac{27}{14}$

b)

$\frac{ \frac{8}{3} }{ \frac{5}{9} } = \frac{8}{3}. \frac{9}{5} = \frac{8.3}{5} = \frac{24}{5}$

c)

$\frac{ \frac{12}{5} }{ \frac{6}{7} } = \frac{12}{5}. \frac{7}{6} = \frac{2.7}{5} = \frac{14}{5}$

d)

$\frac{ \frac{13}{12} }{ \frac{2}{5} } = \frac{13}{12}. \frac{5}{2} = \frac{65}{24}$
