Explicação passo a passo:

1 -(1/6-1/3) :(1/6 + 1/2)+4/9.9/2

{1-(1/6-2/6):(1/6+3/6)+2}

1-(-1/6):4/6+2

1+1/6.6/4+2

=3+1/4

= 13/4

Answer 2

= 1 - (1/6-1/3) : (1/6 + 1/2)+4/9.9/2 = 1 - [1-2]/6 : [1+3]/6 ={1-(1/6-2/6):(1/6+3/6)+2} = 1-(-1/6):4/6+2 = 1+1/6.6/4+2 = 1+6/24 (:6)/(:6)+2 =3+1/4 = (4.3+1)/4 = 13/4
