Answer 1

Resposta:

Explicação passo a passo:

Calcule:

a)

1/2+2/3: (3.1+2.2)/6= (3+4)/6

= 7/6

__________

b)1/3 + 4/6 (:2)/(:2):

1/3 + 2/3 = 3/3

= 1

_____________

c)3/4+5/6:

Mmc (4,6)= 12

= (3.3+2.5)/12

= (9+10)/12

= 19/12

______________

d)3/2 . (3/3)+5/6:

= 9/6 + 5/6

= 14/6 (:2)/(:2)

= 7/3

___________

e)4/6 (:2)/(:2) - 1/3:

= 2/3-1/3

= 1/3

_________

f)4/6 (:2)/(:2) - 3/4: ​

= 2/3 - 3/4

= (4.2 - 3.3)/12

= (8-9)/12

= - 1/12
