• $\frac{8}{5}$
• $\frac{9}{22}$
• $\frac{10}{21}$Explicación paso a paso

$\frac{1}{9} \times \frac{1}{2} = \\ = \frac{1 \times 1}{9 \times 2} \\ = \frac{1}{18}$

$\frac{4}{5} \div \frac{1}{2} = \\ = \frac{4 \times 2}{5 \times 1} \\ = \frac{8}{5}$

$\frac{1}{2} \times \frac{9}{11} = \\ = \frac{1 \times 9}{2 \times 11} \\ = \frac{9}{22}$

$\frac{2}{7} \div \frac{3}{5} = \\ = \frac{2 \times 5}{7 \times 3} \\ = \frac{10}{21}$
