Answer 1

Explicação passo-a-passo:

$a) \frac{7}{6} \div \frac{3}{2} = \frac{7}{6} \times \frac{2}{3} = \frac{7 \times 2}{6 \times 3} = \frac{14}{18} = \div \frac{2}{2} = \frac{7}{9}$

$b) \frac{1}{2} \times \frac{4}{5} = \frac{1 \times 4}{2 \times 5} = \frac{4}{10} = \div \frac{2}{2} = \frac{2}{5}$

$c) \frac{3}{7} \times \frac{3}{9} = \frac{3 \times 3}{7 \times 9} = \frac{9}{63} \div \frac{9}{9} = \frac{1}{7}$

$d) \frac{3}{1} \times \frac{8}{3} = \frac{3 \times 8}{1 \times 3} = \frac{24}{3} = 8$

$e) \frac{4}{7} \times \frac{7}{9} = \frac{4 \times 7}{7 \times 9} = \frac{28}{63}$
