Answer 1

$\displaystyle\bf\\1)\\\\\frac{m^{2} }{5} \cdot\frac{2}{m^{4} } =\frac{m^{2}\cdot 2 }{5\cdot m^{2} \cdot m^{2} } =\frac{2}{5m^{2} } \\\\\\\frac{12}{a^{2} } \cdot\frac{a}{3} =\frac{3\cdot 4\cdot a}{a\cdot a\cdot 3}=\frac{4}{a} \\\\\\2)\\\\\frac{p}{5} :\frac{p}{3}=\frac{p}{5} \cdot\frac{3}{p} =\frac{3}{5} =0,6\\\\\\\frac{3}{a^{2} }:\frac{9}{a} =\frac{3}{a^{2} } \cdot\frac{a}{9} =\frac{3\cdot a}{a\cdot a\cdot 3\cdot 3} =\frac{1}{3a}$
