As we know, the absolute value does not pay any attention to sign/direction. It focuses mainly on the distance (quantity).
l0/9l = 0/9
That is because that's the distance, not including the sign.
Answer: 0/9
221 is rational since 221 = 221/1
So is 331 because 331 = 331/1
The product of any two rational numbers is also rational
--------------------------
Proof:
Let x = p/q and y = r/s be two rational numbers. The q and s values are nonzero.
Their product is
x*y = (p/q)*(r/s)
x*y = (p*q)/(r*s)
which is a ratio of two integers pq and rs, so (p*q)/(r*s) is rational
