This is my understanding of finding the relative minor of a major scale is by using the 6 scale degree. So 1) The relative minor to the Key of D would be the Key of Bm. 2) The relative minor to the Key of A would be the key of F#m.

3) To find the relative Major to a Minor Key I would use the 3 scale degree. So the relative Major to the Key of Am would be the Key of C
