Prove that a, b, c, and d are rational numbers where a b c d are non zero integerbe z. steps reasons 1. a over b mins c over d given 2. ad over bd plus cb over bd multiply to get a common denominator 3. simplify fill in the missing step in the proof. ad times cb all over bd ad plus cb all over bd ad minus cb all over bd ad plus cb all over two times bd
