  1. Answer:

    We can say that rational numbers are closed under addition, subtraction and multiplication. For example: (7/6)+(2/5) = 47/30. 2) No, rational numbers are not closed under division. … As a division of two rational numbers 2 and 0 is not a rational number, so the division of two rational numbers is not closed.
