Пошаговое объяснение:
№ 1
-1. 1/15 : 4. 4/5 = -16/15 : 24/5 = -16/15 * 5/24 = -2/3 * 1/3 = -2/9
№2
-1,2х = -3,6
х = -3,6 : -1,2
х = 3
№3
1/3 : х = -2/9
х = 1/3 : (-2/9)
х = 1/3 * (-9/2)
х = 1/1 * (-3/2)
х = -3/2
х = -1. 1/2
1. -1 1/15:4 4/5 =(-16/15):(24/5)=-16*5/(15*24)=- 2/9
2. -1,2х=-3,6
х=-3,6/(-1,2)
х=3
3. 1/3:х=-2/9
х=-(1/3)/(2/9)
х=-3/2
х=-1 1/2
