Answer 1

To determine which numbers are rational, we look for numbers that can be expressed as a fraction (where both the numerator and denominator are integers, and the denominator is not zero).

Let's evaluate each number:

1. **√14**: This is an irrational number because it cannot be expressed as a fraction of two integers.

2. **2.7**: This is a rational number because it can be expressed as 27/10.

3. **√36**: This is a rational number because it equals 6, which can be expressed as 6/1.

4. **√72**: This is an irrational number because it cannot be expressed as a simple fraction (approximately 8.485).

5. **11/23**: This is a rational number because it is already expressed as a fraction of two integers.

6. **π**: This is an irrational number because it cannot be expressed as a fraction of two integers.

From this evaluation, the numbers that are rational are:

- **2.7**
- **√36**
- **11/23**

So, the three that apply are **2.7, √36, and 11/23.**
