1ra tarea de pensamiento algebraico, 1-4. turno:matutino.

Resolver los siguientes ejercicios, escribiendo el procedimiento:
1. 3+4+5-6-7-4+7-4+9= 7
2. -6+4-6+2-9-8+2+3+6-8-12-43+67= -10
3 (2)(-12)(3)(3)(-2)(1)(3)= 1296
4. (-2)(3)(1)(-4)(5)(6)(-7)(-8)= 40320
5. -4+5-6+7-8+9-12+24-33(2)(-3)(4)(5)= 1920

Números Racionales
6. (3/4)+(5/9)= 47/30
7. (6/2)-14/4)= -4/8 = -2/4 = -1/2
8. (3/5)(12/3) - (4/7)(6/11)= 2412/1165 = 804/385
9. (((4/3)(6/2)/(4/4)))+(2/5) + 3/4 - 16/7= 9624/3360 = 2406/840
10. (18/5)(9/2) + 25/3 - 6/4 - 7/15 = 20760/1800 = 3460/300
11. (14/3)/(23/11) + 9/6(5/4)= 6690/1656 = 1115/276
12. (((5/25)(16/2)/(25/7)(13/6))/(12/7) + 3/2 = 632040/390000 = 105340/65000


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

2.- -6+2=-4-6=-10+2=-8-9=-17=-8-25+2=-23+3=-20+6=-14-8=-22-12=-34-43=-77+67=-10

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

4.-(-2)(3)=-6(1)=-6(-4)=24(5)=120(68)=720(-7)-5040(-8)=40320

5.- -4+5=1-6=-5+7=4-8=-4+9=5-12=-7+24=17-33=-16(2)=-32(-3)=96(4)=384(5)=1920

6.- 27 + 20 / 36 = 47/30

7.- 24 - 28 / 8 =-4/8
-4/8 = -2/4 = -1/2

8.- (36/15) - (24/77) = 2772
2772- 360 / 1155 = 2412/1155
2412/1155 = 804/385

9.- (24/6) / (4/4)= 96/24
(96/24) + (2/5)= 480 + 48 / 120= 528/120
(528/120) + (3/4)= 2112 + 360 / 480= 2472/480
(24/72) - (16/7)= 17304 - 7680 / 3360= 9624/3360
9624/3360 = 2406/840 (cuarta)

10.- (18/5) (9/2)= 162/10
(162/10) + (25/3)= 480 + 250 / 120= 330/30
(330/30) - (6/4)= 1320 - 180 / 120= 1140/120
(1140/120) - (7/15)=21600 - 840 / 1800= 20760/1800
20760/1800 = 3460/300 (sexta)

11.- (14/3) / (23/11)= 154/69
(154/69) + (9/6)= 924 + 414 / 414= 1338/414
(1338/414) (5/4)= 6690/1656
6690/1656 = 1115/276 (sexta)

12.- (5/25) (16/2)= 80/50
(80/50) / (25/7) (13/6)= (80/50) / (325/42)
(80/50) / (325/42)= 3360/16250
(3360/16250) / (12/7)= 23520/195000
(23520/195000) + (3/2)= 47040 + 585000 / 390000= 632040/390000
632040/390000 = 105340/65000 (sexta)
