Answer 1

Explicação passo-a-passo:

$a) \frac{4}{5} \times \frac{3}{8} = \frac{12}{40} = \frac{6}{20} = \frac{3}{10} \\ \\ b) \frac{2}{7} \times \frac{14}{6} = \frac{28}{42} = \frac{14}{21} = \frac{2}{3} \\ \\ c) \frac{5}{6} \times \frac{4}{5} = \frac{20}{30} = \frac{10}{15 } = \frac{2}{3} \\ \\ d) \frac{8}{9} \times \frac{6}{10} = \frac{48}{90} = \frac{24}{45} = \frac{8}{15} \\ \\ e) \frac{8}{5} \times \frac{4}{6} = \frac{32}{30} = \frac{16}{15} \\ \\ f) \frac{7}{6} \times \frac{3}{14} = \frac{21}{84} = \frac{7}{28} = \frac{1}{4} \\ \\ g) \frac{21}{8} \times \frac{4}{7} = \frac{84}{56} = \frac{42}{28} = \frac{21}{14} = \frac{3}{2} \\ \\ h) \frac{15}{6} \times \frac{9}{20} = \frac{135}{120} = \frac{45}{40} = \frac{9}{8}$
