To determine which of the given numbers are rational, let's analyze each option:
1. **1.28** - This is a terminating decimal, so it is a rational number.
2. **\( \frac{2}{7} \)** - This is a fraction, so it is also a rational number.
3. **\( \sqrt{6} \)** - This is an irrational number because it cannot be expressed as a fraction of two integers.
4. **\( \sqrt{25} \)** - This is equal to 5, which is a whole number and is therefore rational.
So, the rational numbers from the options provided are:
- 1.28
- \( \frac{2}{7} \)
- \( \sqrt{25} \)
In conclusion, the rational numbers are **1.28, \( \frac{2}{7} \), and \( \sqrt{25} \)**.
