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.

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).


Fractions with different denominators are called?

unlike fractions


What are Fractions that have different denominators?

unlike fractions


How do you subtract fractions without alike denominators?

Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.


What the difference between like and unlike fraction?

fractions having same denominators are like fractions & others are unlike fractions


What way is subracting fractions with unlike denominators like adding fractions with unlike denominators?

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.


What is the word for fractions with different denominators?

Unlike. Unlike. Unlike. Unlike.


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 the definition of unlike fractions?

That simply means that the fractions have different denominators. Such fractions cannot be directly added, subtracted, or compared; you have to convert them to a common denominator first.


What do like and unlike fractions mean?

Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.


When adding fractions with unlike denominators it is most helpful if the fractions are renamed using the?

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.


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.
