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.

Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.
You must have 2 fractions or more to have unlike fractions. They are fractions with different denominators such as 7/8 and 1/2. Like fractions would have the same denominator like 7/8 and 4/8.
because you can not add unlike thingsTo get the right answer. It's not immediately obvious what the sum of 1/2 and 1/3 is. But if you realize that 1/2 = 3/6 and 1/3 = 2/6, then 1/2 + 1/3 = 3/6 + 2/6 = 5/6
Yes, you can. For example 3x times 4y = 12xy.You cannot however, add like terms (to combine them, that is. There isn't anything wrong with adding them up, 3x + 4y is acceptable). For example, 3x + 4y is as simplified as it can get.
What is the definition of Adding and Subtracting Like Fractions
Anything having to do with adding or subtracting unlike fractions.

Finding the LCM will make adding and subtracting fractions easier.
When adding two or more unlike fractions, yes.
you must make the fractions equivalent and with the same denomenator
Use the LCM when you are adding and subtracting unlike fractions. Use the GCF when you are simplifying fractions.
first u find a common denominator
If you are adding or subtracting unlike fractions, convert them to equivalent fractions with a common denominator.
When adding unlike fractions, find the LCM of the denominators and convert them to it.
Find the lowest common denominator
Finding the LCM helps in the process of adding and subtracting unlike fractions.
