Answer 1

Respuesta:

1. $\frac{3}{6} \div \frac{5}{6} = \frac{3}{6} \times \frac{5}{6} = \frac{3}{5}$
2. $\frac{7}{11} \div \frac{14}{44} = \frac{7}{11} \times \frac{14}{44} = \frac{7}{11} \times \frac{22}{7} = \frac{7 \times 22}{11 \times 7} = \frac{22}{11} = 2$
3. $\frac{18}{14} \div \frac{12}{20} = \frac{18}{14} \times \frac{12}{20} = \frac{18}{14} = \frac{9}{7} = \frac{20}{12} = \frac{5}{3} = \frac{9}{7} \times \frac{5}{3} = \frac{3}{7} \times \frac{5}{1} = \frac{3 \times 5}{7 \times 1} = \frac{15}{7 \times 1} = \frac{15}{7}</li><li>$
4. $\frac{20}{13} \div \frac{10}{4} = \frac{20}{3} \times \frac{4}{10} = \frac{2}{3} \times \frac{4}{1} = \frac{2 \times 4}{3 \times 1} = \frac{8}{3 \times 1} = \frac{8}{3}$
5. $\frac{13}{5} \div \frac{39}{20} = \frac{13}{5} \times \frac{20}{39} = \frac{13 \times 20}{5 \times 39} = \frac{260}{5 \times 39} = \frac{260}{195} = \frac{4}{3}$
6. $\frac{35}{4} \div \frac{21}{8} = \frac{35}{4} \div \frac{8}{21} = \frac{35 \times 8}{4 \times 21} = \frac{280}{4 \times 21} = \frac{280}{84} = \frac{10}{3}$
