When adding two or more unlike fractions, yes.

I'm really sorry I've done this before but i just totally am thinking the same exact thing!

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator.

The first step is to make the denominators the same.

Like fractions have the same denominator, unlike fractions don't.
