Перетворіть на дріб вираз:

1) (15m^2)/22 • 11/10m = (15m^2 • 11)/(22 • 10m) = 3m/4;
2) 6p/7 • (2,5c^2)/(15p^3 ) = (6p • 2,5c^2)/(7 • 15p^3 ) = (15c^3)/(7 • 15p^2 ) = c^2/(7p^2 );
3) 15/xp • x^2/45 = (15x^2)/(xp • 45) = x/3p;
4) 4a/p^2 • (–p/(8a^2 )) = –4ap/(8a^2 p^2 ) = –1/2ap;
5) –(5c^2)/7y • 49y/(10c^3 ) = –(5c^2• 49y)/(7y • 10c^3 ) = –7/2c;
6) –(6a^2)/(65b^2 ) • (–13b/30a) = (6a^2 • 13b)/(65b^2 • 30a) = a/25b.
