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.
Fractions with different denominators are called?
unlike fractions
What are Fractions that have different denominators?
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 definition of adding and subtracting fractions with unlike denominators?
What is the definition of Adding and Subtracting Like 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.
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.
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!
Fractions with different denominators are called?
unlike fractions
What are Fractions that have different denominators?
unlike fractions
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.
How do you add or subtract fractions with unlike denominators?
convert at least one of them so that they have the same denominator, then proceed with the addition or subtraction
What the difference between like and unlike fraction?
fractions having same denominators are like fractions & others are unlike fractions
What is the word for fractions with different denominators?
Unlike. Unlike. Unlike. Unlike.
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.
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 do like and unlike fractions mean?
Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.
