No one w/ a clear understanding of 7th grade math would be confused, the rules are unambiguous and usually reviewed the first week or two of the school year all the way through 9th grade
1/(2x) is not equivalent to (1/2)x

division is not associative, you cannot add parentheses as you can w/ multiplication

1*2*x = (1*2)*x = 1*(2*x) =1(2*x) = 1(2x) = 1*(2x) because multiplication is associative
