Answer 2

¡Hola!

Respuesta:

$Es\:b)\frac{21}{40}$

Explicación paso a paso:

$\left(\frac{1}{2}\cdot \frac{3}{4}\cdot \frac{4}{3}\right)\div \left(\frac{4}{7}\cdot \frac{2}{3}\cdot \frac{5}{2}\right)\\\\\left(\frac{1\cdot \:3\cdot \:4}{2\cdot \:4\cdot \:3}\right)\div \left(\frac{4\cdot \:2\cdot \:5}{7\cdot \:3\cdot \:2}\right)\\\\\left(\frac{1\cdot \:4}{2\cdot \:4}\right)\div \left(\frac{4\cdot \:5}{7\cdot \:3}\right)\\\\\left(\frac{20}{7\cdot \:3}\right)\div \left(\frac{21}{2\cdot \:20}\right)\\\\\frac{20}{21}\div \frac{21}{40}\\\\\frac{1}{2}\div \frac{21}{40}$

$\frac{21}{40}$
