Adding Fractions

Adding Like Fractions


You can add fractions easily if the bottom number (the denominator) is the same: /4 (One-Quarter)
1

/4 (One-Quarter)

/4 (Two-Quarters)

/2 (One-Half)

Another example:
5

/8

/8

/8

/4

Adding Unlike Fractions OR Adding Fractions with Different Denominators


But what if the denominators (the bottom numbers) are not the same? As in this example:
3

/8

/4

You must somehow make the denominators the same. In this case it is easy, because we know that 1/4 is the same as 2/8 :
3

/8

/8

/8

But it can be harder to make the denominators the same, so you may need to use one of these methods (they both work, use whichever you prefer):

Least Common Denominator, or Common Denominator
