6. (3/4)+(5/9)=
3/4+5/9=27+20/36= RESULTADO=47/36



7. (6/2)-14/4)=6/2-14/4=24-28/8=-4/8=-2/4= RESULTADO=-1/2



8. (3/5)(12/3) - (4/7)(6/11)=
36/15-24/77=2772-361/1155= RESULTADO=2412/1155


9. (((4/3)(6/2)/(4/4)))+(2/5) + 3/4 - 16/7=(24/6)/(4/4)=96/24+2/5=475+48/120=623/120+3/4=2492+360/480=2852/480-16/7= 19964-7680/3360=12284/3360=6142/1680= RESULTADO=3071/840

10. (18/5)(9/2) + 25/3 - 6/4 - 7/15 =
(18/5)(9/2)+25/3=486+250/30=736/30-6/4=2944-180/120=2764/120-7/15=41460-840/1800=40620/1800= RESULTADO=20310/900

11. (14/3)/(23/11) + 9/6(5/4)=
154/69+45/24=3696+3105/1656=6801/1656= RESULTADO=2267/552

12. (((5/25)(16/2)/(25/7)(13/6))/(12/7) + 3/2 =
(80/50)/(325/42)=(3360/16250)/(12/7)=23520/195000+3/2=47040+585000/390000=632040/390000=316020/195000=158010/97500=79005/48750=26335/16250 RESULTADO=5267/3250
