## Make sure the bottom numbers (denominators) are the same

In order to add fractions the denominators must be the same.

``3/4 + 1/2``

You'll need to find the least common multiple (LCM) of the denominators (4 and 2). The least common multiple is 4, so the least common denominator is 4.

Since the last common denominator is 4, we need to change our fraction 1/2 to 2/4.

So our new problem is:

``3/4 + 2/4``

In our problem:

``3/4 + 2/4``

we have two numerators - 3 and 2. We can add these together and put them over the denominator to get 5/4.

## Simplify the fraction (if needed)

Our answer is 5/4 which can't be simplified, but sometimes you'll need to reduce your answer to its simplest form.
