it stay the same when you subtract fractions and when you add fractions.

if it has a denominator

Yes, you are.

numerators you add, denominators you leave it the same

no, to add and subtract like and unlike fractions the denominator has to be the same,

You can add or subtract fractions only if they are "like" fractions, that is, only if they have the same denominator - unless you know your fractions really well.

In order to add or subtract fractions, they must have the same denominator.

Like Fractions

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. Then add and simplify.

To add fractions, you cannot simply add the numberators and add the denominators. To add fractions, they must first have the same denominator. Once they have the same denominator, you can then simply add the numerators.

You have to convert them to equivalent similar fractions (fractions with the same denominator) first.
