48 ÷2(3+9) = 2
48 ÷2 * (3+9) = 288
Since the equation in question is written as the top example, that is "llikely" the answer that they are looking for. You could make a very strong argument for either case.
Funny thing is, I went and looked in an old math book to see how they answered a like equation. I could not find one written like the above (they would put the extra 48 ÷(2(3+9)) or( 48 ÷2)(3+9) but never without them.)
