7/6 - (20/30)  ---> sacamos decima

7/6 - 2/3 ---> Multiplico a 2/3 (x2)

7/6 - 2(2)/3(2)

7/6 - 4/6 = 3/6 (sacamos tercia) = 1/2 Rtpa

 

(1(3)/2(3)-2(2)/3(2))1/4 + 1/5/1/6

(3/6 - 4/6)1/4 + 6/5

(-1/6)1/4 + 6/5

-1/24 + 6/5 --> Aspa

-5/120 + 144/120 --> -5(120) + 144(120)/ (120)(120) = 17880/14400 = 1,2416..en fraccion ( 12416 - 1241 ) / 9000 = 11175/9000

 

 

(1/6 + 1/4)1/2= (4/24 + 6/24) = (10/24)1/2 = 5/24 Rpta
