Answer 1

Respuesta:

$\frac{-20}{7}\div \frac{-6}{9}\\\\\\\frac{-20}{7}\times \frac{9}{-6}\\\\\\-\frac{20}{7}\times \frac{9}{-6}\\\\\\-\frac{20}{7}\left(-\frac{3}{2}\right)\\\\\\\frac{20}{7}\times \frac{3}{2}\\\\\\\frac{10}{7}\times \frac{3}{1}\\\\\\\frac{10\times \:3}{7\times \:1}\\\\\\\frac{30}{7\times \:1}\\\\\\\frac{30}{7}$

No te olvides...

Regla de fracciones <3...

$\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}\\\\\\\frac{-a}{b}=-\frac{a}{b}\\\\\\\frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}$
