Find the lowest common denominator
you must make the fractions equivalent and with the same denomenator
What is the definition of Adding and Subtracting Like Fractions
Finding the LCM will make adding and subtracting fractions easier.
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.
Anything having to do with adding or subtracting unlike fractions.
When adding two or more unlike fractions, yes.

Adding fractions with like denominators is straightforward, as you simply add the numerators while keeping the denominator the same. In contrast, adding fractions with unlike denominators requires finding a common denominator, which involves identifying the least common multiple of the denominators. Once a common denominator is established, you convert each fraction accordingly before adding the numerators. This extra step makes the process more complex compared to adding fractions with like denominators.
I'm really sorry I've done this before but i just totally am thinking the same exact thing!
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.
