Explicación paso a paso:

$a) \frac{5}{3} (\frac{1}{3} -\frac{5}{6})= \frac{5}{3} .\frac{1}{3} -\frac{5}{3} .\frac{5}{6} =\frac{5}{9} -\frac{25}{18} =\frac{10-25}{18} =-\frac{15}{18}=-\frac{5}{6}$

$b) -\frac{2}{5} (-\frac{3}{8} +\frac{10}{3})= (-\frac{2}{5}) .(-\frac{3}{8}) +(-\frac{2}{5} ).(+\frac{10}{3}) =\frac{6}{40} -\frac{20}{15} =\frac{18-160}{120} =-\frac{142}{120}=-\frac{71}{60}$

$c) \frac{2}{3} (\frac{10}{3} -6+\frac{3}{4})= \frac{2}{3} .\frac{10}{3} -\frac{2}{3}.6+\frac{2}{3} .\frac{3}{4} =\frac{20}{9} -\frac{12}{3}+\frac{6}{12} =\frac{80-144+18}{36} =-\frac{46}{36}=-\frac{23}{18}$

$d) -\frac{2}{5} (-\frac{1}{4} -\frac{5}{8} +10+\frac{1}{6})= (-\frac{2}{5}) .(-\frac{1}{4}) +( -\frac{2}{5}).(-\frac{5}{8}) +(-\frac{2}{5}).10+(-\frac{2}{5}) .\frac{1}{6} =\frac{2}{20} +\frac{10}{40}-\frac{20}{5}-\frac{2}{30} =\frac{12+30-480-8}{120} =-\frac{446}{120}=-\frac{223}{60}$
