8. + + = 20 15 16 12 9 8 6 4 3 Equivalent Equivalent Multiples of 3 and 4
12 is the LCM =

9. When the Denominators are Different
We must get the denominators the same!
How?
Make EQUIVALENT FRACTIONS
Example:
𝟏 𝟒 + 𝟏 𝟑
What is the LCM of 4 and 3?
This is our common denominator!
𝟏 𝟒 𝟏 𝟑 12
𝟑+𝟒 𝟏𝟐 = 𝟕 𝟏𝟐
x 3
x 4
x 3
x 4

10. Example 2: 6 7 − 3 4 24−21 28 = 3 28 What is the LCM of 7 and 4 ? 28
This is our common denominator!
24− = 3 28 28
