To solve for the answer of the question above, let x be the number of words on the list. As stated above, 2/3 of this is the number of words Martina needs to memorize which is 12. This may be expressed as,
                             (2/3)(x) = 12
Solving for x in the equation gives an answer of 18. Therefore, there are 18 words on the list.
