Question

1 si 2/3-[1- 1/12+(2-1 si 3/4)-1/2]+(2-2/3) =

Answer 1

1 si 2/3-[1- 1/12+(2-1 si 3/4)-1/2]+(2-2/3) =
= 5/3 - [12/12 - 1/12 + (8/4 - 7/4) - 6/12] + ( 6/3 -2/3)=
=5/3 - ( 11/12 +1/4 - 6/12) +4/3=
=5/3 - ( 11/12 +3/12 - 6/12)  + 4/3=
=5/3 - 8/12 +4/3 = 
=5/3 -2/3 +4/3=
=7/3=
=2 intregi si 1/3
=2,(3)

Answer 2

1 si 2/3-[1- 1/12+(2-1 si 3/4)-1/2]+(2-2/3) =
= 5/3 - [12/12 - 1/12 + (8/4 - 7/4) - 6/12] + ( 6/3 -2/3)=
=5/3 - ( 11/12 +1/4 - 6/12) +4/3=
=5/3 - ( 11/12 +3/12 - 6/12) + 4/3=
=5/3 - 8/12 +4/3 =
=5/3 -2/3 +4/3=
=7/3=
=2 intregi si 1/3
=2,(3)
