Adding Fractions with Unlike
Denominators
*The first step to add fractions with different
denominators, is to find the least common
denominator (LCD). An easy way to do this, is to list
the multiples of each denominator.
Lets find the multiples of 2 and 3. To do
this, simply multiply the number 2 by 1,2,3,4 and so
on, until a common number is identified.
In the below example, the common number between
2 and 3 is 6.
2: 2, 4, 6, 8, 10
3: 3, 6, 9, 12, 15

Adding Fractions with Unlike
Denominators
Step 1. Determine the multiples of 4 and 7
4: 4, 8, 12, 16, 20, 24, 28, 32
7: 7, 14, 21, 28, 35
Common denominator= 28
Step 2. Set up your equation like the one
shown to the right, with the new
denominator.
