Question

ATIVIDADE 6. Agora, realize as divisões envolvendo as frações:
​

Answer 1

A)

$\frac{2}{5} \div \frac{7}{3} = \frac{2}{5} \times \frac{3}{7} = \frac{6 ^{ \div 6} }{12 ^{ \div 6} } = \frac{1}{2}$

C)

$\frac{6}{7} \div \frac{3}{2} = \frac{6}{7} \times \frac{2}{3} = \frac{12 ^{ \div 3} }{21 ^{ \div 3} } = \frac{4}{7}$

E)

$\frac{9}{3} \div \frac{4}{7} = \frac{9}{3} \times \frac{7}{4} = \frac{63 ^{ \div 3} }{12 ^{ \div 3} } = \frac{21}{4}$
