Подайте у вигляді дробу:

1) (12m^2)/(7c^4 ) : (6m^4)/(35c^3 ) = (12m^2 • 35c^3)/(7c^4 • 6m^4 ) = 10/(cm^2 );
2) (9m^2)/(22n^3 ) : (–m^5/(11n^6 )) = –(9m^2 • 11n^6)/(22n^3 • m^5 ) = –(9n^3)/(2m^3 );
3) –7ab/4cd : (21a^2 b)/(8cd^3 ) = –(7ab • 8cd^3)/(4cd • 21a^2 b) = –(2d^2)/3a;
4) –(27m^2 n)/(7c^2 x) : (–(9mn^2)/(7c^2 x^3 )) = (27m^2 n • 7c^2 x^3)/(7c^2 x • 9mn^2 ) = (3x^2 m)/n.
