**Adding Fractions with Unlike Denominators:**

Remember that given a fraction, such as _{}, the top number is the numerator (namely 1) and the bottom
number is the denominator (namely 2)

Example 1:

_{}

Whenever you add fractions with *unlike*
denominators, you need to make the **denominators** equal to each other by
finding the least common denominator.
In this example, you need to multiply _{} by 5 to get _{}. Next, you need to
multiply the second equation _{}by 4 to get _{}. Note that both fractions now have a common denominator.
Add in the same manner as with the unit Adding fractions
with like denominators.

_{}

Example 2:

_{}_{}

Whenever you add fractions with *unlike*
denominators, you must make the** denominators **of the same value. In this example, the easiest approach is to
multiply 8 x 3 to get 24. Here, you
multiply by 3 to get _{}. Then you multiply
the second equation _{} by 8 to get _{}. Note that both
addends have 24 as a denominator. Add in the same manner as with the unit Adding
fractions with like denominators.
