Помогите решить ( 3 1/4 - 0,25 - 1 5/24 ) : ( 2 3/4 - 4 1/2 - 0,75 ) : (-4 7/12)

Answer 1

( 3 1/4 - 0,25 - 1 5/24 ) : ( 2 3/4 - 4 1/2 - 0,75 ) : (-4 7/12)=19/99

1) 3 1/4-0,25=13/4-1/4=12/4=3

2) 3-15/24= 2 9/24

3) 2 3/4 - 4 1/2= 11/4 - 18/4= - 7/4

4) -7/4-0,75=-7/4-3/4=-11/4

5) 2 9/24 : (-11/4)=57/24 * (-4/11)= -19/22

6) -19/22 : (-4 1/2)= -19/22 * (-2/9)=19/99
