Explicación paso a paso:

$\frac{3}{1}\cdot \frac{5}{6}-\frac{4}{1}\div \frac{8}{3}+7\\\\\frac{\frac{3}{1}\cdot \frac{5}{6}-\frac{4}{1}}{\frac{8}{3}+7}\\\\=\frac{-\frac{3}{2}}{\frac{8}{3}+7}\\\\\frac{-\frac{3}{2}}{\frac{29}{3}}\\\\-\frac{3\cdot \:3}{2\cdot \:29}\\\\-\frac{9}{2\cdot \:29}\\\\=-\frac{9}{58}$

$\frac{5}{2}-\frac{3}{4}+\frac{4}{1}\:\cdot \left(\frac{5}{1}-\frac{1}{2}\right)\\\\\frac{5}{2}-\frac{3}{4}+4\left(\frac{5}{1}-\frac{1}{2}\right)\\\\\frac{5}{2}-\frac{3}{4}+4\left(5-\frac{1}{2}\right)\\\\\frac{5}{2}-\frac{3}{4}+4\cdot \frac{9}{2}\\\\\frac{5}{2}-\frac{3}{4}+18\\\\= \frac{79}{4}$
