Скоротіть дріб: 1) (6x-24y)/4x = (2(3x-12y))/4x = (3x-12y)/2x; 2) (ac+ bc)/3c = (c(a+ b))/3c = (a+ b)/3; 3) (bx- by)/2bc = (b(x- y))/2bc = (x- y)/2c; 4) (6y-6z)/(y- z) = (6(y- z))/(y- z) = 6; 5) (11x+22y)/(22ay+ ax) = (11(x+2y))/(a(2y+ x)) = 11/a; 6) (5x-25y)/(15y-3x) = (5(x-5y))/(3(5y- x)) = –(5(x-5y))/(3(x-5y)) = –5/3.
