Reducing Fractions To Simplest Form

🔑 Key Concepts

• A fraction is in simplest form when the numerator and denominator have no common factors other than 1.
• You can reduce fractions by identifying a common factor.
• One method is to write factor pairs and cross out the common factor.
• Another method is to divide both numbers by the greatest common factor (GCF).
• Both methods produce the same simplified fraction.

✏️ Worked Examples – Reducing Fractions to Lowest Terms

🧠 Math Vocabulary

• Common factor: a number that divides evenly into both the numerator and denominator.
• Greatest common factor (GCF): the largest factor shared by two numbers.
• Factor pair: two numbers multiplied together to make a product.
• Simplest form: a fraction whose numerator and denominator have no common factor other than 1.
• Reduce: to rewrite a fraction in an equivalent simpler form.
• Equivalent fractions: fractions that have the same value even though they look different.

💡 Main Idea

Reducing a fraction means rewriting it in simplest form. This can be done by identifying a common factor and dividing both numbers, or by writing factor pairs and crossing out the common factor.
