Respuesta:

$\frac{?}{?} \times \frac{4}{9} </p><p> = \frac{8}{3} \\ \frac{?}{?} = \frac{8}{3} \div \frac{4}{9} \\ \frac{?}{?} = \frac{8}{3} \times \frac{9}{4} \\ \frac{?}{?} = \frac{72}{12} = \frac{6}{1}$

$\frac{2}{5} \times \frac{?}{?} = \frac{4}{3} \\ \frac{?}{?} = \frac{4}{3} \div \frac{2}{5} \\ \frac{?}{?} = \frac{4}{3} \times \frac{5}{2} \\ \frac{?}{?} = \frac{20}{6} \\ \frac{?}{?} = \frac{10}{3}$

$\frac{8}{9} \times \frac{?}{?} = \frac{2}{3} \\ \frac{?}{?} = \frac{2}{3} \div \frac{8}{9} \\ \frac{?}{?} = \frac{2}{3} \times \frac{9}{8} \\ \frac{?}{?} = \frac{18}{24} \\ \frac{?}{?} = \frac{3}{4}$

$10 \times \frac{?}{?} = 6 \\ \frac{?}{?} = 6 \div 10 \\ \frac{?}{?} = 0.6 \\ \frac{?}{?} = \frac{6}{10}$

$25 \times \frac{?}{?} = \frac{15}{2} \\ \frac{?}{?} = \frac{15}{2} \div 25 \\ \frac{?}{?} = \frac{15}{2} \times \frac{1}{25} \\ \frac{?}{?} = \frac{15}{50} \\ \frac{?}{?} = \frac{3}{10}$

$\frac{?}{?} \times \frac{12}{35} = \frac{2}{5} \\ \frac{?}{?} = \frac{2}{5} \div \frac{12}{35} \\ \frac{?}{?} = \frac{2}{5} \times \frac{35}{12} \\ \frac{?}{?} = \frac{70}{60} \\ \frac{?}{?} = \frac{6}{7}$
