Answer 1

Respuesta:

$a) \frac{2}{3} \times \frac{3}{5} = \frac{2}{5}$

$b) \frac{10}{15} \times \frac{9}{5} = \frac{2}{3} \times \frac{9}{5} = \frac{6}{5}$

$c) \frac{32}{25} \times \frac{15}{4} = \frac{8}{25} \times 15 = \frac{8}{5} \times 3 = \frac{24}{5}$

$d) \frac{11}{8} \div \frac{16}{3} = \frac{11}{8} \times \frac{3}{16} = \frac{33}{128}$

$e) \frac{7}{27} \div \frac{3}{63} = \frac{7}{27} \times \frac{63}{3} = \frac{7}{3} \times \frac{7}{3} = \frac{49}{9}$

$f) \frac{14}{12} \div \frac{21}{15} = \frac{14}{12} \times \frac{15}{21} = \frac{7}{6} \times \frac{5}{7} = \frac{5}{6}$
