Скоротіть дріб:

1) (a-b)/(2(b-a)) = (a-b)/(-2(a-b)) = –1/2;
2) (3x-6y)/(4y-2x) = (3(x-2y))/(-2(x-2y)) = –3/2;
3) (m^2- 5mn)/(15n-3m) = (m(m-5n))/(-3(m-5n)) = –m/3;
4) (7a^4- a^3 b)/(b^4- 7ab^3 ) = (a^3 (7a-b))/(-b^3 (7a-b)) = –a^3/b^3 ;
5) (x^2- 25)/(5x^2- x^3 ) = ((x-5)(x+5))/(-x^2 (x-5)) = –(x+5)/x^2 ;
6) (y^2- 12y+36)/(36- y^2 ) = ((y-6)^6)/(-(y^2- 36)) = ((y-6)(y-6))/(-(y-6)(y+6)) = –(y-6)/(y+6) = (6-y)/(y+6).
