How do you subtract fractions without alike denominators?
Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.
How do you write fractions with common denominators?
multiply the denominators
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.
When do you have to use the common denominators?
You use them when there are 2 fractions with different denominators.
Why can't unlike fractions be added without common denominators?
Because trying to add them without a common denominator would yield an incorrect answer.

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 do you order fractions with unlike denominators?
You can convert them to equivalent fractions with like denominators, then simply compare the numerators.You might also convert each fraction to a decimal (divide the numerator by the denominator); then you can also compare them.
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 least common denominator of two fractions?
The least common denominator is the least common multiple of the denominators of the fractions.
What is an common multiple of the denominators for two or more fractions?
Multiplying the denominators together of two or more unlike fractions will get you a common multiple.
Fractions with unlike denominators and no common factors to have common denominators?
Multiply them by each other.
What is a name for fractions with different common denominators?
Dissimilar fractions.
When do you have to use the common denominators?
You use them when there are 2 fractions with different denominators.
Why can't unlike fractions be added without common denominators?
Because trying to add them without a common denominator would yield an incorrect answer.
