Order of operations fun! Multiplication and division are both on the same level, and this is why this conundrum occurs. Either of these can technically be the correct answer.
Technically, in this kind of scenario, it's more common to go from left to right, hence you'll end up with 6/2 = 3, then multiply that by what's inside of the parentheses (3), coming out to 9.
The argument that leads to an answer of 1 should also be acceptable.
