Rational Numbers

🔹 What Is It?

A rational number is any number that can be written as a fraction — one number over another.

🧩 Clue to Remember

Rational = Ratio. If it can be a fraction, it’s rational.

🔹 Example

• One-half
  
  

• Three over four
  
  

• Negative five over two
  
  

• Zero
  
  

• Even 1.75 (because it’s 7 over 4)
  
  

💡 Why It Matters

Rational numbers include most of the numbers we use in money, measurement, and everyday calculations.
