Question

Calcula (1-1/5):(1+1/5)
(1-2/5)×(2/3-1/2)
(1-2/3):(1-4/3)
(1+1/8)×(2-16/9)
(3/4-2/3)×(2-2/7)
(1/2-1/3):(1-5/6)
(4/3-2/5):(4/5-1/2)
(2/3-1/2):(1/3-1/5)​

Answer 1

Espero que te ayude :)

Explicación paso a paso:

$(1-1/5):(1+1/5)=(4/5):(6/5)=20/30=2/3\\(1-2/5).(2/3-1/2)=(3/5).(1/6)=3/30=1/10\\(1-2/3):(1-4/3)=(1/3):(-1/3)=-3/3=-1\\(1+1/8).(2-16/9)=(9/8).(2/9)=18/72=1/4\\(3/4-2/3).(2-2/7)=(1/12).(12/7)=12/84=1/7\\(1/2-1/3):(1-5/6)=(1/6):(1/6)=6/6=1\\(4/3-2/5):(4/5-1/2)=(14/15):(3/10)=140/45=28/9\\(2/3-1/2):(1/3-1/5)=(1/6):(2/15)=15/12=5/4$
