I get 1/16. I buy the idea that “2x” means “(2*x)”
I don’t buy that “2(9+3)” means “(2*(9 + 3))”
2ers are assuming that the “/” makes some sort of impenetrable boundary and that it is “2” and only “2” that is being distributed.
I think “48/2” is being distributed across (9 + 3).
(48/2)* 9 + (48/2) * 3
216 + 72
288
