Answer 1

$\displaystyle\bf\\1)\\\\\frac{42m^{2} }{p^{5} } :(7mp)=\frac{42m^{2} }{p^{5} } \cdot\frac{1}{7mp} =\frac{7m\cdot6m}{p^{5} \cdot7m\cdot p} =\boxed{\frac{6m}{p^{6} } }\\\\2 )\\\\\frac{5}{a^{2} } :\frac{9}{b^{4} } =\frac{5}{a^{2} } \cdot\frac{b^{4} }{9} =\boxed{\frac{5b^{4} }{9a^{2} } }\\\\3)\\\\\frac{a^{2} }{17} :\frac{a^{2} }{7} =\frac{a^{2} }{17} \cdot\frac{7}{a^{2} } =\boxed{\frac{7}{17} }$
