Answer 2

Explicación paso a paso:

42/5 : 11/21

$\frac{42}{5}\div \frac{11}{21} = \frac{42}{5}\times \frac{21}{11} = \frac{42 \times 21}{5 \times 11} = \frac{882}{55}$

100/8 : 20 /5

$\frac{100}{8}\div \frac{20}{5} = \frac{100}{8}\times \frac{5}{20} = \frac{100 \times 5}{8 \times 20} = \frac{500}{160} = \frac{25}{8}$

22/10 : 66/5

$\frac{22}{10}\div \frac{66}{5} = \frac{22}{10}\times \frac{5}{66} = \frac{22 \times 5}{10 \times 66} = \frac{110}{660} = \frac{1}{6}$
