The relationship between rational numbers and whole numbers can be understood in the context of their definitions:
1. **Rational Numbers**: A rational number is any number that can be expressed as the quotient or fraction \(\frac{a}{b}\), where \(a\) is an integer and \(b\) is a non-zero integer. Rational numbers include integers, fractions, and repeating or terminating decimals. For example, \(\frac{1}{2}\), \(-3\), and \(0.75\) are all rational numbers.
2. **Whole Numbers**: Whole numbers are non-negative integers, which include \(0\) and all positive integers (0, 1, 2, 3, ...). Whole numbers do not include any fractions or negative numbers.
### Relationship:
- **Are all rational numbers also whole numbers?**
No, not all rational numbers are whole numbers. For example, \(\frac{1}{2}\) is a rational number, but it is not a whole number because it is not a non-negative integer.
- **Are all whole numbers also rational numbers?**
Yes, all whole numbers are rational numbers. Each whole number can be expressed as a fraction with a denominator of 1. For example, the whole number \(5\) can be represented as \(\frac{5}{1}\), which confirms that it is indeed a rational number.
### Examples:
- A rational number that is **not a whole number**: \(-3\) (a rational number, but negative) and \(\frac{1}{3}\) (a fraction).
- A whole number that is also a rational number: \(0\) (which can be expressed as \(\frac{0}{1}\)), \(4\) (which can be expressed as \(\frac{4}{1}\)), and \(10\) (which can be expressed as \(\frac{10}{1}\)).
In summary, all whole numbers are rational numbers, but not all rational numbers are whole numbers.

Can you simplify it?

Sure! Here’s a simplified explanation of the relationship between rational numbers and whole numbers:
1. **Definitions**:
- **Rational Numbers**: Numbers that can be expressed as a fraction \(\frac{a}{b}\) where \(a\) is an integer and \(b\) is a non-zero integer (e.g., \(-2\), \(\frac{1}{2}\), \(0.75\)).
- **Whole Numbers**: Non-negative integers (0, 1, 2, 3, ...).
2. **Key Points**:
- **Not all rational numbers are whole numbers**: For example, \(\frac{1}{2}\) and \(-3\) are rational numbers, but they are not whole numbers.
- **All whole numbers are rational numbers**: Every whole number can be written as a fraction (like \(5\) as \(\frac{5}{1}\)).
### Examples:
- **Rational but not whole**: \(\frac{1}{2}\) and \(-3\).
- **Whole but also rational**: \(0\), \(4\), and \(10\).
In summary, while all whole numbers are rational numbers, not all rational numbers are whole numbers.
1. **Definitions**:
- **Rational Numbers**: Numbers that can be expressed as a fraction \(\frac{a}{b}\) where \(a\) is an integer and \(b\) is a non-zero integer (e.g., \(-2\), \(\frac{1}{2}\), \(0.75\)).
- **Whole Numbers**: Non-negative integers (0, 1, 2, 3, ...).
2. **Key Points**:
- **Not all rational numbers are whole numbers**: For example, \(\frac{1}{2}\) and \(-3\) are rational numbers, but they are not whole numbers.
- **All whole numbers are rational numbers**: Every whole number can be written as a fraction (like \(5\) as \(\frac{5}{1}\)).
### Examples:
- **Rational but not whole**: \(\frac{1}{2}\) and \(-3\).

Can you give a summary?

Certainly! Here’s a concise summary of the relationship between rational numbers and whole numbers:
- **Rational Numbers** are numbers that can be expressed as fractions \(\frac{a}{b}\) (where \(a\) is an integer and \(b\) is a non-zero integer). Examples include \(-2\), \(\frac{1}{2}\), and \(0.75\).
- **Whole Numbers** are non-negative integers (0, 1, 2, 3, ...).
### Key Points:
- Not all rational numbers are whole numbers (e.g., \(\frac{1}{2}\) and \(-3\)).
- All whole numbers are rational numbers (e.g., \(0\) is \(\frac{0}{1}\), and \(5\) is \(\frac{5}{1}\)).
In summary, the main relationship is that while every whole number is a rational number, not every rational number is a whole number.
