1/ 1) -0.6х*(-5m+n-8a)=3xm-0.6nx+4.8xa

превратим смешанные числа в неправильные дроби и умножим почленно на 12:

2) ((5a/4)-b/6+(7c/3))*12=15а-2b+28c

2. 1) (10a+15x-25y)=5*(2a+3x-5y)

2)3ax-9am+3a=3a*(x-3m+1)

Пошаговое объяснение:

№4

1) = 3хm - 0,6xn + 4,8xa

2) = (5/4a - 1/6b + 7/3c) * 12 = 60/4a - 12/6b + 84/3c = 15a - 2b + 28c

№5

1) = 5(2a + 3x - 5y)

2) = 3a(x - 3m + 1)
