Answer 2

Rational numbers are numbers that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. Let's check each of the given numbers:

1. **–19**: This can be expressed as –19/1, which is a fraction of integers.
**Rational**

2. **Negative two-fifths**: This is written as –2/5, which is a fraction of integers.
**Rational**

3. **0**: This can be expressed as 0/1, which is a fraction of integers.
**Rational**

4. **StartFraction 4 Over 7 EndFraction**: This is written as 4/7, which is a fraction of integers.
**Rational**

5. **1.091502…**: This is a repeating decimal (if we assume the sequence continues) and can be expressed as a fraction. Thus, it is rational as it has a finite or repeating decimal representation.
**Rational**

6. **2.89**: This is a terminating decimal, which can be expressed as 289/100, a fraction of integers.
**Rational**

Therefore, all of the options listed are rational numbers.

Answer 3

The following numbers are rational:

- –19
- Negative two-fifths
- 0
- \( \frac{4}{7} \)
- 1.091502…
- 2.89

**All the numbers listed are rational.**
