if it has a denominator

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

numerators you add, denominators you leave it 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.

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 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.

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.

You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.
