Скоротіть дріб:

1) (3x-3y)/(x- y) = (3(x- y))/(x- y) = 3;
2) (4x+4y)/(a(x+ y)) = (4(x+ y))/(a(x+ y)) = 4/a;
3) (3x-6y)/(2x-4y) = (3(x-2y))/(2(x-2y)) = 1,5;
4) (5a-5b)/(b- a) = –(5(a- b))/(a- b) = –5;
5) (3a-9c)/(3c- a) = –(3(a-3c))/(a-3c) = –3;
6) (4x-12y)/(3ay- ax) = (4(x-3y))/(a(3y- x)) = –(4(x-3y))/(x-3y) = –4;
7) (a^2- ab)/(b^2- ab) = (a(a- b))/(b(b- a)) = –(a(a- b))/(b(a- b)) = –a/b;
8) (2ax-2ay)/(3bx-3bx) = (2a(x- y))/(3b(y- x)) = –(2a(x- y))/(3b(x- y)) = –2a/3b.
