There are no rational numbers.

Answer 1

Rational numbers: A, B, C, D, E, F.

Reasons:
- A (−5) and D (8) and C (0) are integers, hence rational.
- E (12/7) and B (7/4) are ratios of integers, so rational.
- F (4.\overline{45} = 4.454545...) is a repeating decimal, so rational.
- G (π) is irrational. H is false.
