Common multiples and common denominators can be found using the same process. They differ in their function. Common denominators are common multiples that are functioning as denominators.

How are common multiple and a common denominator alike and different?
Common denominators are multiples that are being used as denominators. The process to find them is the same.
How are a common denominator and a common multiple different?
They are essentially the same. A common denominator is the common multiple of a set of denominators of a set of fractions.
Does a common denominator have to be the same denominator?
A common denominator results from comparing two or more unlike denominators. It can be the same as one of the denominators, but doesn't have to be.
Explain how comparing fractions with like denominators differs from comparing fractions with unlike denominators?
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).
How are all unit fractions alike and different?
Unit fractions all have the same numerators but the denominators can be different.
How are common multiple and a common denominator alike and different?
Common denominators are multiples that are being used as denominators. The process to find them is the same.
Why would the least common multiples help us with fraction addition?
Least common multiples and lowest common denominators are essentially the same thing. Once the denominators are the same, it's easier to get the correct answer when adding and subtracting fractions.
What is the differeince between common factors and common multiples?
Common factors go into the numbers, the numbers go into common multiples.
What is the purpose of learning least common multiples?
When subtracting or adding fractions the denominators must be the same if they are not then the LCM must be found.
When you subtract fractions do you subtract the denominator?
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
How are a common denominator and a common multiple different?
They are essentially the same. A common denominator is the common multiple of a set of denominators of a set of fractions.
What is the process of subtracting fractions?
If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.
How do you minnous fractions?
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

How is adding like fractions and adding unlike fractions the same?
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.
How do you add if the numerators are the same and the denominators are different?
You have to make the fractions equivalent, which means you need to find the lowest common factor that goes into both the denominators.
When denominators are the same?
They are not different.
What does it mean to get a common denominator?
Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.
