1 is the correct answer, as it preserves the integrity of the horizontal bar symbol to indicate to division, which also implicitly qualifies the order of operations, according to which you always do what's in parentheses first, so the expression would instantly become, "6 divide by 2 times 3. In real life we were told to qualify explicitly, by enclosing in parentheses. So, "6 divide by the quantity, 2 times 3", which yields 1. There would be no question of order of operations using the bar: 6/(2 times 3). The arithmetic order of operations specification seems clear that division is done last.
