Пошаговое объяснение:

3) (5 5/28- 5 1/3*1,25-1 16/21):(-1,5)

5 1/3*1,25=16/3*5/4=20/3=6 2/3

5 5/28-6 2/3=5 15/84-6 56/84=-1 41/84

-1 41/84-1 16/21=-1 41/84-1 64/84=-2 105/84=-3 1/4

-3 1/4:(-1.5)=-13/4*(-2/3)=13/6=2 1/6



4) (-3 1/3*1,9+19,5:4 1/3):(0,16-62/75)

-3 1/3*1,9=-10/3*19/10=-19/3=-6 1/3

19,5:4 1/3=39/2*3/13=9/2=4 1/2

-6 1/3+4 1/2=-6 2/6+4 3/6=-1 5/6

0,16-62/75=4/25-62/75=12/75-62/75=-50/75=-2/3

-1 5/6:(-2/3)=-11/6*(-3/2)=11/4=2 3/4
