Quién me ayuda porfa

Answer 1

Respuesta:

$- \frac{2}{3} \div \frac{4}{5} = \frac{ - 2 \times 5}{3 \times 4} = \frac{ - 10}{12} = \frac{ - 5}{6}$

$\frac{1}{5} \div \frac{ - 6}{7} = \frac{1 \times 7}{5 \times - 6} = \frac{7}{ - 30}$

$\frac{7}{12} \div \frac{2}{5} = \frac{7 \times 5}{12 \times 2} = \frac{35}{24}$

$\frac{ - 5}{4} \div \frac{ - 3}{7} = \frac{ - 5 \times 7}{4 \times - 3} = \frac{ - 35}{ - 12} = \frac{35}{12}$
