All rational numbers are also integers

Answer 1

Correct: "All natural numbers are also integers."

Explanation: Every natural number (1, 2, 3, … — and 0 in some definitions) is an integer. The other statements are false because:
- Natural numbers are rational (n = n/1), so "Not all natural numbers are rational" is false.
- Irrational numbers are not rational by definition.
- Not all rational numbers are integers (e.g., 1/2 is rational but not an integer).
