Resolva as expressões numéricas:
a)4: (2\5 + 1\5)=
b)5\6 + 1\3 : 2 -0,3=
c)1\2 :3\5 . 1\3=
d)1- 1\3 + 1\6=

Answer 1

Resposta:

a)  20/3

b)  0, 68

c)  5/2

d)  5/6

Explicação passo a passo:

a) 4 : ( 2/5 + 1 /5 ) =

4 : ( 2 + 1 / 5 ) =

4 : 3/5 =

4 . 5/3 =  20/3

b) 5/6 +  1/3  :  2 - 0, 3 =

5 + 2 / 6  :  1, 7 =

7/6  :  1, 7 =

1, 16  :  1, 7 =  0, 68

c) 1/2 : 3/5 . 1/3 =

1/2 : 3/15 =

1/2 . 15/3 =

15/6 ( simplificando por 3)

5/2

d) 1 - 1/3 + 1/6 =

6 - 2 + 1 / 6 =

7 - 2 / 6   =   5/6
