There is no justification for rewriting the expression, just to obtain your preferred answer. 6/2(2+1) is the written expression given. in order to obtain the answer 1, it would have to be written 6/[2(2+1)]=1 and this would also be written:
6
------- = 1
2(2+1)
However, the given expression 6/2(2+1)=9 is written:
6
--- (2+1)=9
