To add fractions, you have to find their common denominator by multiplying the two denominators together and one of the numerators to the others. Then you add just the top numbers together.
By eliminating the fractions
The first step, to add, subtract, or compare fractions, is always to convert the fractions to equivalent fractions, that all have the same denominator. You can use one of several techniques to get the LEAST common denominator, or simply multiply the two denominators to get a common denominator (which in this case may, or may not, be the smallest common denominator).
In fractions, you can NEVER add or subtract
Change them into mixed numbers and add the integers and fractions together ensuring that the fractions have a common denominator.
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.

Finding factors is the first step in finding the GCF and the LCM. They will help you to reduce fractions, or add and subtract them.
it stay the same when you subtract fractions and when you add fractions.

Fractions! Otherwise you don't have anything to add.

No.
When adding or subtracting fractions with different denominators, the first step is to find a common denominator. This involves finding the least common multiple (LCM) of the two denominators. Once you have a common denominator, you can then add or subtract the numerators of the fractions accordingly.
