If the fractions have the same denominator, the sum of their numerators (top parts) is the numerator of the result. For the denominator (bottom part), just copy the common denominator. Example: 1/7 + 2/7 = 3/7
The Lowest Common Denominator is needed when adding or subtracting fractions.
You must first convert the fractions to a common denominator. Then just add the numerators (the top part of the fraction).
The first step is to find the lowest common denominator of the fractions.
Same as for adding: If the denominators are not equal, you must first find a common denominator, then convert both fractions to that common denominator.
When adding or subtracting fractions with different denominators, it is necessary to find a common denominator to solve the equation. A common denominator is like a common multiple, except its function is as the bottom number in a fraction.
8 is.

That depends on the other denominator. You need at least two.

You can only add like to like. There is no mechanism for adding different types of fraction.

First find a common denominator. Then, add the numerators together. Simplify if possible.
When adding or subtracting fractions with different denominators, it is necessary to find a common denominator to solve the equation. A common denominator is like a common multiple, except its function is as the bottom number in a fraction.
When adding fractions, you only add the numerators if the denominators are the same. If the denominators are different, you must first find a common denominator before adding the numerators. Once you have a common denominator, you can add the numerators together and keep the common denominator the same. Finally, simplify the resulting fraction if possible.
It can help by when finding the LCD (Least Common Denominator) you find the least number they have in common then that number is your equivalent fraction.
