Is -5.5 a rational number that is not an integer written as a decimal

Yes, \(-5.5\) is a **rational number** that is **not an integer** and is written as a **decimal**. Here's why:

1. **Rational number**: A number is rational if it can be written as a fraction of two integers. In this case:
   \[
   -5.5 = \frac{-11}{2}
   \]
   Since \(-11\) and \(2\) are integers, \(-5.5\) is a rational number.

2. **Not an integer**: An integer is a whole number (positive, negative, or zero). Since \(-5.5\) is not a whole number (it has a decimal part), it is not an integer.

3. **Written as a decimal**: \(-5.5\) is already in decimal form.

1. What is the difference between rational and irrational numbers?
2. Can all decimals be expressed as fractions?
3. Is \(-5.5\) a terminating or repeating decimal?
4. How would you express \(-5.5\) as a mixed number?
5. What are examples of irrational numbers that cannot be written as fractions?

**Tip**: Any decimal that either terminates or repeats is a rational number!
