When there are different denominators in fractions, to add them, it is necessary to find a common denominator. Usually this occurs by multiplying them, such as 1/3 + 1/2 would equal 2/6 + 3/6, which becomes 5/6.

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.

What is three eighths plus one fourth?
The denominators are different, so find the equivalent fractions using the LCD , then add the fractions with the denominators.
How do you Add rational expressions with common denominators and binomial numerators?
If the denominator is the same, you just add the numerators - just as with plain numbers.
What is a unlike fraction?
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.
When you add or subtract fractions with unlike denominators why do you have to find LCM?
Because to add fractions, the denominators must be equal.
How do you add and subtract unlike denominators?
you make them have like denominators by multiplying so many times that they have the same denominators or you can make them have like denominators by multiplying the two
How does using fraction strips with like denominators make it possible to add fractions with unlike denominators?
because they are the same number

Why do fractions need to have unlike denominator before you add or subtract them?
The question is based on a complete misunderstanding of what is required. Unlike denominators are NOT required!
When adding fractions with unlike denominators it is most helpful if the fractions are renamed using the?

What is the definition to unlike denominators?
unlike denominators: the bottom number of a fraction. to have unlike denominators you must have two fractions with a different number on the bottom of each fraction.
Explain why you cannot add fractions with unlike denominators?
You can totally add fractions with unlike denominators. You have to first find the LCD (least common denominator) to make them the same denomintars. And then you can just simply add them. What you cannot do is add fractions with unlike denominators without changing them to fractions with like denominators. The reason being that you would be attempting to add fractions that are different sizes. 1/2 is not the same size as 1/3, so it would be like trying to add apples and oranges. You have to change them to a common size and that is the reason you have to find the least common denominator first. While you cannot add 1/2 and 1/3, you can add 3/6 and 2/6.
How do you add and subtract mixed numbers with unlike denominators?
just change the fration with the smallest denominator and add or subtract the way you always do.
What is the word for fractions with different denominators?
Unlike. Unlike. Unlike. Unlike.
What is the benefit of getting the least common multiple of two or more numbers?
It will enable you to add and subtract fractions with unlike denominators.
