OK

The key here is Order of Operations. Since you do not have ( ) you must use the order of operations.

SO accordingly, ...

6 - (4/12) + (8/6)
6 - (1/3) + (1 1/3)
7

I get 7 as the answer.

Hope that helps.

1st interpretation:
= ([{6 - 4}/12] + 8)/6
= ([2/12] + 8)/6
= ([1/6] + 8)/6
= (1/6 + 48/6)/6
= 1/6(49/6)
= 49/36 or 1 13/36

Answer: 49/36 or 1 13/36

2nd interpretation:
= ([6 - 4]/[12 + 8])/6
= (2/20)/6
= 1/6(1/10)
= 1/60

Answer: 1/60

3rd interpretation:
= 6 - 4/12 + 8/6
= 6 - 1/3 + 4/3
= 6 + 1
= 7

Answer: 7

4th interpretation:
= (6 - 4)/([12 + 8]/6)
= 2/(20/6)
= 2/(10/3)
= 2(3/10)
= 3/5

5th interpretation:
= 6 - ([4/{12 + 8}]/6)
= 6 - ([2/20]/6)
= 6 - ([1/10]/6)
= 6 - (1/60)
= 360/60 - 1/60
= 359/60 or 5 59/60

Answer: 5 59/60

Without the proper use of parenthesis, brackets ([]) and or braces ({}) there will be doubts on the part of the answerer as to what the asker is trying to achieve.

Brackets must be used to clarify question.
6 - (4/12) + (8/6) is but a GUESS at what you mean.
6 - 1/3 + 4/3
6 + 3/3
6 + 1
7

However you may mean :-
(6 - 4) / 12 + 8 / 6
2 / 12 + 8 / 6
1 / 6 + 8 / 6
9 / 6
3 / 2

Tip
Present questions CLEARLY.

6 - 4/12 + 8/6
= 6 - 1/3 + 4/3
= 18/3 - 1/3 + 4/3
= 17/3 + 4/3
= 21/3
= 7

In the problem, you have to use order of operations.
And yes, the / means the divide sign.

So 6 - (4/12) + (8/6)
becomes 6 - (1/3) + (4/3)

6 + [-(1/3) + (4/3)] >>>>> 6 + (3/3)
6+ 1 = 7

when we have this kind of expression or when we have to evaluate the mathematical expression then we use BODMAS RULE
BO=> Bracket off
D=>Divide
M=>Multiply
A=>Addition
S=>Subtraction

In the above order we solve the expression
so
in your question first of all we solve divide and then addition and finally subtraction look as follows
6 - 4/12 + 8/6
=>6 - 0.33 + 1.33
=> 7.33 -0.33
=> 7.00 (answer)

arent u supposed to be using pedmas??
what section are you learning? it really would help.
isn't this supposed to be prealg??

i got "7"
2008-09-01 12:26 pm
6 - 1/3 + 4/3 = 6 + 3/3 = 6 + 1 = 7
2008-09-01 12:25 pm
6 - 4 / 12 + 8 / 6 = ?
6 - (1/3) + (4/3) = ?
6 + 1 = 7

there's your answer dude, i hope. i'm gonna feel stupid if it isn't
