Question 1036567
<pre>
One-third of a number is twelve less than one-half of the number. 

                {{{expr(1/3)N}}}{{{""=""}}}{{{expr(1/2)N - 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.
