Explicación paso a paso:

e) $(32)/(0) =$sin definir

$\frac{a}{0} =$no esta definida

f) $\frac{13}{8} /(-\frac{11}{8} )= -\frac{13}{11}\quad \left(\mathrm{Decimal:\quad }\:-1.18181\dots \right)$

$\mathrm{Aplicar\:las\:propiedades\:de\:las\:fracciones}:\quad \frac{a}{-b}=-\frac{a}{b}$

$=-\frac{\frac{13}{8}}{\frac{11}{8}}$

$\mathrm{Aplicar\:las\:propiedades\:de\:las\:fracciones}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}$

$\frac{\frac{13}{8}}{\frac{11}{8}}=\frac{13\cdot \:8}{8\cdot \:11}$

$=-\frac{13\cdot \:8}{8\cdot \:11}\\\mathrm{Eliminar\:los\:terminos\:comunes:}\:8\\=-\frac{13}{11}$

g) $(-\frac{3}{15} )/(-\frac{10}{9} ) =\frac{9}{50}\quad \left(\mathrm{Decimal:\quad }\:0.18\right)$

$\mathrm{Aplicar\:las\:propiedades\:de\:las\:fracciones}:\quad \frac{-a}{-b}=\frac{a}{b}\\=\frac{\frac{3}{15}}{\frac{10}{9}}\\=\frac{\frac{1}{5}}{\frac{10}{9}}\\\mathrm{Aplicar\:las\:propiedades\:de\:las\:fracciones}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}\\\frac{1\cdot \:9}{5\cdot \:10}\\=\frac{9}{5\cdot \:10}=\frac{9}{50}$

h) $(\frac{24}{7})/(\frac{11}{6}) =\frac{144}{77}\quad \left(\mathrm{Decimal:\quad }\:1.87012\dots \right)$

$\frac{\frac{24}{7}}{\frac{11}{6}} \\\mathrm{Aplicar\:las\:propiedades\:de\:las\:fracciones}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}\\=\frac{24\cdot \:6}{7\cdot \:11}\\multiplicas \\=\frac{144}{77}$

i) $(-\frac{4}{9})/(-3\frac{1}{6}) = \frac{8}{57}\quad \left(\mathrm{Decimal:\quad }\:0.14035\dots \right)$

$convertir numerosmixtos: 3\frac{1}{6}=\frac{19}{6}\\=\frac{\left(-\frac{4}{9}\right)}{\left(-\frac{19}{6}\right)}\\\mathrm{Aplicar\:las\:propiedades\:de\:las\:fracciones}:\quad \frac{-a}{-b}=\frac{a}{b}\\=\frac{\frac{4}{9}}{\frac{19}{6}}\\\mathrm{Aplicar\:las\:propiedades\:de\:las\:fracciones}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}\\=\frac{4\cdot \:6}{9\cdot \:19}\\=\frac{8}{57}$

j)$(2\frac{3}{5})/(-\frac{25}{14}) =-1\frac{57}{125}\quad \left(\mathrm{Decimal:\quad }\:-1.456\right)\\\mathrm{Aplicar\:las\:propiedades\:de\:las\:fracciones}:\quad \frac{a}{-b}=-\frac{a}{b}\\=-\frac{\frac{13}{5}}{\frac{25}{14}}\\\mathrm{Aplicar\:las\:propiedades\:de\:las\:fracciones}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}\\\frac{\frac{13}{5}}{\frac{25}{14}}=\frac{13\cdot \:14}{5\cdot \:25}\\=-\frac{13\cdot \:14}{5\cdot \:25}\\=-\frac{182}{125}\\ =-1\f\frac{57}{125}$

espero haber ayudado :)
