Alguém pode me ajudar?

Answer 1

Resposta:7/6

Explicação passo-a-passo:

(2/3)+(1/3)+(2/12)=?

Calcule o mmc de cada denominador:

3,3| 3

1,1 |

(2/3)+(1/3)+(2/12)=

2+1/3+2/12=

Simplifique a fração 2/12 por 2:

2÷2= 1

--- ---

12÷2= 6

(2/3)+(1/3)+(2/12)=

2+1/3+2/12=

2+1/3+1/6=

Some os numeradores (2,1):

(2/3)+(1/3)+(2/12)=

2+1/3+2/12=

2+1/3+1/6=

3/3+1/6=

Simplifique a fração "3/3" por 3:

3÷3= 1

--- ----

3÷3= 1

(2/3)+(1/3)+(2/12)=

2+1/3+2/12=

2+1/3+1/6=

3/3+1/6=

1/1+1/6=

Calcule o mmc de 1,6,e resolva:

1,6 |6

1,1

(2/3)+(1/3)+(2/12)=

2+1/3+2/12=

2+1/3+1/6=

3/3+1/6=

1/1+1/6=

6+1/6=

7/6
