tarea 2

resolver los siguientes ejercicios

Resolver los siguientes ejercicios

1.- ((6/14)(2/13)/(5/2))+ 2/7 =142/455
12/182 / 5/2 = 24/910 = 12/455 + 2/7 = 84+910/3185=142/455

2.- 9/7 + 6/5 -18/12 -1/5 =11/14
45+42/35 = 87/35
-18/12-1/5 =-90-12/60=-102/60=51/30=-17/10
87/35-17/10=11/14

3.- 3/9 - 16/4 +25 = 64/3
-11/3+25/1= -11+75/3= 64/3

4.- 25 - 16 - 48 - 76 + 65 + 82 - 45 + 12 =

6.- 11/3 + 22/8 -3/4 =
77/12-3/4= 308- 36/48= 272/48=136/24=68/12=34/6=17/3

7.- ((13/6)(33/4)/(19/16)) + 22 -18 =362/19
429/24/19/16=6864/456=1716/114=572/38+22/1 =572+836/38=1408/38
1408/38=704/19-18/1=704-342/19=362/19
