2/3[3(4/6+1/3)-1(2-4)/2]=

2/3[3(2/3+1/3)-1(-2)/2]=

2/3[3(3/3)+2/2]=

2/3[3(1)+1]=

2/3[3+1]=

2/3[4]=

(2/3)(4/1)=

8/3

4[3/5(4/7-3/5)-(5/4+2/3)3/2]=

4 [ 3/5 (20-21/35) - (15+8/12) 3/2 ]=

4 [ 3/5 (- 1/35) - (23/12) 3/2 ]=

4 [ - 3/175 - 69/24 ]=

4 [ -72-12075/4200 ]=

4 [ -12147/4200]=

- 48.588/4200=

- 24294/2100=

- 12147/1050=

- 4049/350=
