Пошаговое объяснение:
1) -4/9*(3/11)*9/16*(-22) = 3/11*(-22) * (-4/9)*9/16 = -6 * (-1/4) = 3/2 = 1 1/2
---------------------
1)-1,2*3a = -3,6a (подчеркни -3,6)
2)-5b*2,4c = -12bc (.........-12)
3)1 3/5x*(-15/32y) = 8/5x *(-15/32y) = -3/4xy (.............-3/4)
--------------------------
1)2*(x-7y+3z) = 2x - 14y + 6z
2)-0,6x*(-5+3m-1,4n) = 3x - 1,8xm + 0,84xn
3)(c-8d+6d) * (-1,5) = -1,5c + 12d - 9d = -1,5c + 3d
====================
1)8a-19a-28a+3a = -36a
2)1,4m-m+n-2,6n = 0,4m - 1,6n
