Answer:

here is your answer

Step-by-step explanation:

(ii) Consider the rational numbers -3/7 and 5/14. Then  

(-3/7 × 5/14) = {(-3) × 5}/(7 × 14) = -15/98, is a rational number .  

(iii) Consider the rational numbers -4/5 and -7/3. Then  

(-4/5 × -7/3) = {(-4) × (-7)}/(5 × 3) = 28/15, is a rational number.
