What else can I help you with?
Do you need a common denominator for all fractions before doing the order of operations?
You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.
Why do you need a common denominator with fractions?
You can add or subtract fractions only if they are "like" fractions, that is, only if they have the same denominator - unless you know your fractions really well.
Why do you need a common denominator when you add fractions?
Unless you are using a calculator that adds them for you, it is much harder to add fractions with uncommon denominators. Having the same denominator allows you to only have to add the numerators for your answer.
When you add fractions do you add the denominator to?
No.
When you add fractions do they have to have the same denominator?
Yes you have to add with the same denominator. when ever you do fractions they have to have the same denominator no matter what. So thats a yes
Why do you need a common denominator?
Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have 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.
Why do you need to use common denominator?
To get the right answer when you add or subtract unlike fractions.
What are compatible numbers for fractions?
I am not entirely sure what you mean, but if you need to add, subtract, or compare two fractions, they need to have the same denominator.
Do you need a common denominator when adding fractions?
Yes, you must convert both fractions to the same denominator to add them. Now... Do the rest of your homework yourself!
How do you add and subtract fractions with the same denominator?
it stay the same when you subtract fractions and when you add fractions.
What is the meaning of addition and subtraction of similar fraction?
Similar fractions are fractions with the same denominator. In order to add or subtract fractions they need to be similar.
Adding unlike fractions?
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.
