Rational Numbers

🔹 What Is It?

Rational numbers are any numbers that can be written as a fraction — including decimals and integers.

🧩 Clue to Remember

If a number can be written as “a number over another number,” it is rational.

🔹 Example

• Fractions like three over four
  
  

• Decimals like zero point five (which is one-half)
  
  

• Integers like negative two (which is negative two over one)
  
  

💡 Why It Matters

Rational numbers let us compare amounts, work with positive and negative values, and solve real-world problems with precision.
