I guess I look at this problem from the reverse :

How would you write these 2 seperate problems in single line form without having the ability to make a fraction or similar character from a standard keyboard device ??

6

------

2(1+2)

6

--- (1+2)

2

I would say that the first one is: 6 / [2(1+2)]

And the second is: (6/2)(1+2)

In both instances, I had to include extra brackets to the original equation to remove any possible source of ambiguity that might come into play with differences of opinions. If you look at the 2 ways I wrote the equations, there is no chance of misinterpretation which therefore tells me the original question was written poorly and leaves room for error. Hence, this drawn out forum over such a simple issue.

My final stance, there is a possibility of 2 correct answers depending on clarification of the original equation for which expressions go where.
