Скоротіть дріб:

1) ( a^2 b^2)/(a b^7 ) = a/( b^4 );
3) (p(a-2))/(m(a-2)) = p/m;
5) (a-2y)/( a^2- 2ay) = (a-2y)/(a(a-2y)) = 1/a;
7) ( x^2- 4x+4)/(3x-6) = ((x-2 )^2)/(3(x-2)) = (x-2)/3;
2) (-63x a^5)/(81x a^6 ) = –7/9a;
4) (7a-14b)/(3a-6b) = (7(a-2b))/(3(a-2b)) = 7/3;
6) ( m^2-1)/(7m+7) = ((m-1)(m+1))/(7(m+1)) = (m-1)/7;
8) ( x^2- 2xy)/(2y-x) = (x(x-2y))/(-(x-2y)) = –x.
