Answer 1

$frac{65}{44}m^3n^2* frac{33}{52}p^4= frac{15}{16}m^3n^2p^4$

$frac{52a^5}{84b^10} : frac{39a}{102b^2} : frac{4a^3}{45b^9}= frac{13a^5}{21b^(10)} : frac{13a}{34b^2} : frac{4a^3}{45b^9} =$

$frac{a^5}{21b^(10)} * frac{34b^2}{a} : frac{4a^3}{45b^9}= frac{a^4}{21b^8} *34: frac{4a^3}{45b^9}= frac{a^4}{21b^8} * 34 * frac{45b^9}{4a^3}=$

$frac{a}{21b^8} *34* frac{45}{4}b^9= frac{1}{21}a *34* frac{45}{4}b= frac{1}{7}a *17* frac{15}{2}b= frac{17*15}{7*2}ab= frac{255}{14}ab$
