2da tarea,de algebra. 1-4 turno, Matutino.

1.- ((6/14)(2/13)/(5/2))+ 2/7 =588/1470=196/490
(6/14)(2/3)=12/42 / 5/2=24/210
24/210 + 2/7=168+420/1470=588/1470
588/1470=196/490 (tercera)

2.- 9/7 + 6/5 -18/12 -1/5 =1650/2100=330/420
9/7 + 6/5=45+42/35=87/35-18/12=1044-630/420=414/420
414/420 - 1/5=2070-420/2100=1650/2100
1650/2100=330/420 (quinta)

3.- 3/9 - 16/4 +25 =768/36=128/6
3/9 - 16/4=12-144/36=-132/36
-132/36 + 25/1=-132+900/36=768/36
768/36=128/6 (sexta)

4.- 25 - 16 - 48 - 76 + 65 + 82 - 45 + 12 =2
25-16=9-48=-39-76=-115+65=-50+82=35-45=-10+12=2

5.- (2)(-9)(3)(-8)(7)(-6)(5)(4)(16)(-2) =-11,612,160
(2)(-9)=-18(3)=-54(-8)=432(7)=3024(-6)=-18144(5)=-90720(4)=-362880(16)=5806080 (-2)=-11,612,160

6.- 11/3 + 22/8 -3/4 =1184/416=296/104
11/13 + 22/8=88+286/104=374/104
374/104 - 3/4=1496-312/416=1184/416
1184/416=296/104 (cuarta)

7.- ((13/6)(33/4)/(19/16)) + 22 -18 =8692/456=2173/114
(13/6)(33/4)=429/24 / 19/16=6864/456
6864/456 + 22/1=6864/10032/456=16869/456
16896/456 - 18/1=16896-8208/456=8692/456
8692/456=2173/114 (cuarta)

8.- 17 - 13 +62 -((33/3)(15/3)/3) =1287/27=429/9
17/1 - 13/1=17-13/1=4/1
4/1 + 62/1=4+62/1=66/1-((33/3)(15/3)/3)
(33/3)(15/3)=495/9 / 3/1= 495/27
66/1 - 495/27=1782-495/27=1287/27
1287/27=429/9 (tercera)


9.- (17)(1/5)(-4)(-6)(-2/7)(1/6)(45/6)(-2)=36720/1260=6120/210
(17/1)(1/5)=17/5(-4/1)=-68/1(-6/1)=408/5
408/5(-2/7)=-804/35(1/6)=-804/210(45/6)=-18360/1260
18360/1260(-2/1)=36720/1260
36720/1260=6120/210 (sexta)

10.- -15 +15 -48 -65 -36 +52 +89 -79 +62 -69 =-94
-15+15=0-48=-48-65=-113-36=-149+52=-97+89=-8-79=-87+62=-25-69=-94
