1. LESSON 4-6 Simplifying Fractions
Page 164

2. Simplify:
Divide the numerator and the denominator by a common factor.
I will show you three different ways to do this problem.
12 divided by 2 = divided by 6 = 1
24 divided by 2= divided by 6 = 2
***Notice divide the numerator and the denominator by the same number!!!!

3. Simplify: 12 24 Find GCF: (Write as prime factorization) 12= 2 x 2 x 3
24= 2 x 2 x 2 x 3
GCF is 2x2x3=12….. So divide each by 12
12 divided by 12 is one
24 divided by 12 is 2…. Answer 1/2

4. Simplify:
Write number as prime factorizations and cross out common numbers.
12= 2 x 2 x 3
24= 2 x 2 x 2 x 3
Cross out what they have in common
What is left? Looks like nothing on top, really is a one because 2 divided by 2 is 1, 3 divided by 3 is 1, answer is ½.
