The number is x
(x/3)+12=(x/2); twelve less means is we add 12 to it, they are equal.
multiply everything by a common denominator of 6.
2x+72=3x
x=72
(1/3) of 72 is 24
that is 12 fewer than 36 which is half 72.
Second choice.

One-third of a number is twelve less than one-half of the number. 

                expr%281%2F3%29N%22%22=%22%22expr%281%2F2%29N+-+12

Multiply through by LCD = 6

                  2N = 3N - 72
                  -N = -72
                   N = 72

Checking the words: 

One-third of 72 is twelve less than one-half of 72.

One-third of 72 is 24
One-half of 72 is 36

24 is 12 less than 36.

So it checks.
