### MJ3

Ch 2.3.2 – Simplifying Fractions (pg. 611)

Bellwork
• Please take out your assignment from yesterday and leave it on your desk so that I can check it.
• Find the GCF
• 6, 18, 40
• 17, 34
Before we begin…
• Yesterday we reviewed how to get the GCF of two or more numbers
• Today we will use what we learned about the GCF to simplify fractions….
Objective
• Students will simplify fractions using the GCF
Simplifying Fractions
• When a rational number is represented by a fraction it is often expressed in simplest form
• A fraction is in its simplest form when the GCF of the numerator and denominator is 1
• There are 2 methods to simplify fractions using the GCF
• Divide by the GCF
• Prime factorization of the numerator and denominator
Dividing by GCF
• Demonstrate on board using 30/45
Using Prime Factorization
• Demonstrate on board using 30/45
