nummeros racionales

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

7. (6/2)- 14/4)=
Maestro sele olvido poner el cuarto parentesis las dos posibles respuestas serian:
( 6/2)-(14/4)=24-28/8 = -4/8=-1/2 o tambien prodria ser:
(6/2)(-14/4)=84/8=21/2

8. (3/5)(12/3)-(4/7)(6/11)=2412/1155
(3/5)(12/3)=36/15
(4/7)(6/11)=24/77
(36/15)-(24/77)=2772-360/1155=2412/1155

9. ((((4/3)(6/2)/(4/4))))+(2/5)+3/4-16/7=401/140
((24/6)/4/4 )+(2/5)+3/4+16/7
(96/24)+(2/5)+(3/4)+16/7
4+(2/5)+(3/4)+16/7=22/5+3/4-16/7
22/5+3/4=88+15/20=130/20
130/20-16=721-320=401/140

10. (18/5)(9/2) + 25/3 - 6/4 - 7/15= 40620/1800
(18/5)(9/2)=162/10 + 25/3 - 6/4 - 7/15
162/10 + 25/3=486+250/30=736/30
736/30 - 6/4 =2944-180/120=2764/120
2764/120 - 7/15= 41460-840/1800=40620/1800


11. (14/3)/(23/11)+9/6(5/4)=6801/1656
154/69 + 9/6 (5/4)=
(9/6)(5/4)=45/25
154/69 + 45/24=3696+3105/1656=6801/1656

12. ((((5/25)(16/2)/(25/7)(13/6))/(12/7)+3/2=5267/3250
(80/50)/(325/42)=3360/16250
(336/1625)/12/7)=2352/19500=196/1625
196/3/2=392+4875/3250=5267/325o
196/1625+3/2=392+4875/3250=5267/3250
