Lesson 3-6 Example Example 2 1.Write the prime factorization of each denominator. 10=2 5 6=2 3

Lesson 3-6 Example Example 2 2.The LCM of the numbers contains only the factors in each number. If there are common factors, include them only one time. The denominators, 10 and 6, have one factor in common, 2. LCD = = 30

Lesson 3-6 Example Example 2 3.Rename each fraction using 30 as the denominator.

Lesson 3-6 Example Example 2 4.Subtract the like fractions.
