Answer 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.

Answer 2

Answer:

No

Step-by-step explanation:

$\frac{6}{8} -\frac{2}{8} \neq \frac{2}{8}-\frac{6}{8}\\\\=\frac{4}{8}\neq \frac{-4}{8}$
