3º tarea de algebra...

1.- ((6/14)(2/13)/(5/2))+ 2/7 =
(6/14)(2/13)=6/91
(6/91)/(5/2)=12/455
12/455+2/7=142/455
el resultado es:142/455

2.- 9/7 + 6/5 -18/12 -1/5 =
9/7+6/5=87/35
87/35-18/12=69/70
69/70-1/5=11/14
el resultado es:11/14

3.- 3/9 - 16/4 +25 =
3/9 16/4=-11/3
(-11/3)+(25)=64/3
el resultado es: 64/3

4.-25 - 16 - 48 - 76 + 65 + 82 - 45 + 12 =
25-16=9
9-48=-39-
39-76=-115
-115+65=-50
-50+82=32
32-45=-13
-13+12=-1
el resultado es: -1

5.-(2)(-9)(3)(-8)(7)(-6)(5)(4)(16)(-2) =
(2)(-9)=-18
(-18)(3)=-54
(-54)(-8)=432
(432)(7)=3024
(3024)(-6)=-18144
(-18144)(5)=-90720
(-90720)(4)=-362880
(-362880)(16)=-5806080
(-5806080)(-2)=11612160
el resultado es: 11612160

6.- 11/3 + 22/8 -3/4 =
11/3+22/8=77/12
77/12-3/4=17/3
el resultado es:17/3

7.-((13/6)(33/4)/(19/16)) + 22 -18 =
(13/6)(33/4)=143/8
(143/8)/(19/16)=286/19
286/19+22=704/19
704/19-18=362/19
el resultado es: 362/19

8.- 17 - 13 +62 -((33/3)(15/3)/3) =
17-13=4
4+62=66
(33/3)(15/3)=495/9
(495/9)/(3)=55/3
66-55/3=143/3
el resultado es: 143/3

9.-(17)(1/5)(-4)(-6)(-2/7)(1/6)(45/6)(-2)=
(17)(1/5)=17/5
(17/5)(-4)=-68/5
(68/5)(-6)=408/5
(408/5)(-2/7)=-816/35
(-816/35)(1/6)=-136/35
(-136/35)(45/6)=-204/7
(-204/7)(-2)=408/7
el resultado es: 408/7

10.--15 +15 -48 -65 -36 +52 +89 -79 +62 -69 =
-15+15=0
0-48=-48
-48-65=-113
-113-36=-152
-152+52=-100
-100+89=-11
-11-79=-90
-90+62=-28
-28-69=-97
el resultado es:-97
