Compare Rational Numbers Graph each rational number on a number line. Mark off equal size increment of between –4 and –3. Answer: The number line shows that . A. > B. < C. = 0% A 1. 2. 3. 0% B A B C 0% C Compare Rational Numbers 12 = 22 ● 3 and 16 = 24. So the LCM is 24 ● 3 or 48. The LCD of 12 and 16 is 48.
