Last week Tom had exams in Math and in Spanish. He had a score of 45 on the Math exam and a score of 65 on the Spanish exam. For which class should Tom expect the better grade?
a. Math
b. Spanish
c. The grades should be the same because the two exam scores are in the same location.
d. There is not enough information to determine which is the better grade.

I'd say "d."
45 out of how many?
65 out of how many? 
d.
