Respuesta:

$\left(3\frac{3}{4}\right)\left(-64\right)\left(4\frac{1}{6}\right)\left(-\frac{1}{10}\right)\\\\\\\left(\frac{15}{4}\right)\left(-64\right)\left(4\frac{1}{6}\right)\left(-\frac{1}{10}\right)\\\\\\\left(\frac{15}{4}\right)\left(-64\right)\left(\frac{25}{6}\right)\left(-\frac{1}{10}\right)\\\\\\\frac{15}{4}\cdot \:64\cdot \frac{25}{6}\cdot \frac{1}{10}\\\\\\\frac{15\cdot \:25\cdot \:1\cdot \:64}{4\cdot \:6\cdot \:10}\\\\\\\frac{24000}{4\cdot \:6\cdot \:10}\\\\\\\frac{24000}{240}\\\\\\100$

No te olvides las formlas..

$\left(a\right)=a,\:-\left(-a\right)=a\\\\\\a\cdot \frac{b}{c}\cdot \frac{d}{e}=\frac{a\:\cdot \:b\:\cdot \:d}{c\:\cdot \:e}$
