Answer 1

3/4+2/3: (-8/12)= 3/4+2/3*(-12/8)= 3/4-1= 3/4-4/4= -1/4


(1/3+2/7)* (1-1/9)+3/7= (7/21+6/21)* (9/9-1/9)+3/7= (13/21*8/9)+3/7= 104/189+3/7= 104/189+81/189= 185/189


-0,75-1 2/3= -3/4-5/3= -9/12-20/12= -29/12= -2 5/12


-14-9      6-12        -23          -6
--------  - ---------- = ----------- - ----- = 23/4- 6/3= 69/12-24/12= 45/12= 15/4
- 4            -3           -4         -3
