numeros racionales

Resolver los siguientes ejercicios, escribiendo el procedimiento:

1. 3+4+5-6-7-4+7-4+9= 7
7 ,12 ,6 ,-1 ,-5 ,2 ,-2

2. -6+4-6+2-9-8+2+3+6-8-12-43+67= -8
-2, -8, -6, -15, -23, -21, -18 -12, -20, -32, -75

3 (2)(-12)(3)(3)(-2)(1)(3)= 1296 -24, -72, -216, 432, 432,


4. (-2)(3)(1)(-4)(5)(6)(-7)(-8)= -40320
-6, 6, -24, -120, -720, 5040


5. -4+5-6+7-8+9-12+24-33(2)(-3)(4)(5)= 2160
1, -5, 2, -6, 3, -9, 15, -18 (-120)


Números Racionales

6. (3/4)+(5/9)= 13/12
27+12/36= 39/36



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


8. (3/5)(12/3) - (4/7)(6/11)=804/385
36/15 - 24/77 =2772 - 360/1155 =2412/1155


9. (((4/3)(6/2)/(4/4)))+(2/5) + 3/4 - 16/7=



10. (1/8/5)(9/2) + 25/3 - 6/4 - 7/15 =991/1050
162/10+25/3=486/250-6/4=1994/1500-7/5= 10500/29910= 4955/5250


11. (14/3)/(23/11) + 9/6(5/4)=2575/552
14/3 . 11/23=154/69+ 9/6 = 924 +621/414=1545/414 . 5/4 =7725/1656

12. (((5/25)(16/2)/(25/7)(13/6))/(12/7) + 3/2 =63040/195
((80/50 entre 325/42)
(3360/16250 entre 12/7) + 3/2
23520/195000+ 3/2 =47040+585000/195000
