Sure! Here's how the numbers can be categorized into "Rational numbers" and "Irrational numbers":
Rational numbers:
- 0
- 3/5
- 2.15
Irrational numbers:
- π (pi)
- 6.239654... (this number can be considered rational if it terminates or repeats, but since the ellipsis suggests it might not, it's often treated as most likely in this context as irrational).
