2.4=12/5
12/5*7/6=14/5
14/5-16/3=-38/15 - первая скобка;
-19.2=-96/5
-96/5-13/3=-353/15
-1.8=-9/5
-353/15-9/5=-380/15=-76/3 - вторая скобка
-38/15 / -76/3=38/15*3/76=1/10=0.1
1)2.4*7/6=2.8=2 4/5
2)2 4/5-5 1/3=-(5 1/3-2 4/5)=-(5 5/15- 2 12/15)=-(4 20/15-2 12/15)=-2 8/15=
-38/15
3) -19.2-1.8-4 1/3=-25 1/3=-76/3
4) (-38/15)/(-76/3)=38*3/(15*76)=0.1
