No, not all rational numbers are integers. Rational numbers are defined as numbers that can be expressed as the quotient of two integers \( \frac{a}{b} \), where \( a \) is an integer, \( b \) is a non-zero integer.
While all integers are rational numbers (since any integer \( n \) can be expressed as \( \frac{n}{1} \)), not all rational numbers are integers.
Here are some examples of rational numbers that are not integers:
1. \( \frac{1}{2} \): This is a rational number because it can be expressed as the quotient of the integers 1 and 2, but it is not an integer.
2. \( \frac{-3}{4} \): This is also a rational number, and it is not an integer.
3. \( \frac{7}{3} \): This rational number is not an integer either, as it does not divide evenly.
In summary, while all integers are rational, there are many rational numbers (such as \( \frac{1}{2} \), \( \frac{-3}{4} \), and \( \frac{7}{3} \)) that are not integers.

Sure! Not all rational numbers are integers.
For example:
- The number 0.5 is a rational number, but it is not an integer.
- The number -0.75 is a rational number, but it is not an integer.
- The number 2.333... (which is 2 and 1/3) is a rational number, but it is also not an integer.
In contrast, integers are whole numbers, such as -1, 0, 1, 2, etc. So while all integers can be considered rational numbers (because they can be expressed as a fraction), many rational numbers are not integers.

Of course!
Not all rational numbers are whole numbers (integers).
For example, think about the number 0.5. It’s a rational number because it can be expressed as a fraction, but it’s not a whole number. Similarly, -0.75 is another example; it’s rational, but it’s not an integer.
On the other hand, numbers like 2, -3, and 0 are integers because they don’t have any fractional parts.
So, while every whole number can be turned into a fraction (like 2 as \( \frac{2}{1} \)), there are plenty of rational numbers that aren’t whole numbers.
