B. 2 Remember PEMDAS; parentheses, exponents, multiplication, division, addition, and subtraction.
288.
PEMDAS - but go left to right for operations...multiplication and division are the same rank, so you do them left to right.
So, parens first, then divide, then multiply...288...

It's 2.
When you have 48 / 2(9+3) You would do the 9+3 first, since it is in parenthesis. Then you multiply that by 2. (Multiplication first) then, you would divide 48 by that.
So 48 / 2(12)
48 / 24

This is correct
(48 ÷ 2) * (9 + 3) = 288
This is correct

Its a matter of whether the 12 is in the numerator or denominator. Clearly its in the numerator. 90% of government educated school kids would probably fail this...wait they use calculators.
And here is a hint: Use a calculator... Unless you have a RPN one it knows what order to perform.

For sure 288. You have to multiply the number outside the parenthesis with the 2 numbers inside them, then add them.
It's not a matter of whether you can or can't do math. It's a matter of how you see what is presented.
If the problem were written as 48 ÷ 2 * (9 + 3), it'd be easier to see: divide 48 by 2, and then multiply the result by the sum of 9 and 3. But the way it's written, some people see it as a fraction with 48 on top and 2(9 + 3) on the bottom, which leads to a different answer.
It's quite simple!

Bingo!
