Question

$( \frac{7}{2} - \frac{5}{2} \times \frac{3}{5} ) \\ .( \frac{3}{8} - \frac{3}{2} \times \frac{7}{5} )$
​

Answer 1

Respuesta:

$(\frac{7}{2} - \frac{5}{2} * \frac{3}{5} )(\frac{3}{8} -\frac{3}{2}* \frac{7}{5} )\\\\(\frac{7}{2}- \frac{15}{10} )(\frac{3}{8}- \frac{21}{10} )\\\\(\frac{35 - 15}{10})(\frac{15 - 84}{40} )\\\\(\frac{20}{10})(-\frac{69}{40} )\\\\(2)(-\frac{69}{40} )\\\\-\frac{138}{40} \\\\-\frac{69}{20}$

Answer 2

Respuesta:

$\left(\frac{7}{2}-\frac{5}{2}\times \frac{5}{3}\right)\cdot \left\left(\frac{3}{8}-\frac{3}{2}\times \frac{7}{5}\right)$

$-\frac{2}{3}\left(\frac{3}{8}-\frac{3}{2}\times \frac{7}{5}\right)$

$-\frac{2}{3}\left(-\frac{69}{40}\right)$

$\frac{23}{20}=1$

$\boxed{\frac{3}{20}}$
