What is the rule for subtracting fractions?
First, change it so that the two fractions have the same denominator (by changing the fractions into equivalent fractions). Once the two fractions have the same denominator, it is simply a case of subtracting the numerators, leaving the denominator the same. Finally, reduce the fraction to its lowest terms (if possible).
When two or more fractions have the same denominator it is called what?
Common denominator
Why is it easier to compare fractions with the same rather than denominator?
If the fractions have different denominators, you need to: 1) Convert to equivalent fractions with a common denominator, 2) Compare the numerators. If the fractions already have the same denominator, there is no need for the first step - which happens to be the most difficult step. Note that as a shortcut, you don't need the LEAST common denominator, any denominator can do. Thus, you can just use the product of the two denominators as the common denominator. As a result, to compare the fractions, you simply multiply the numerator of each fraction by the denominator of the other one, and then compare. However, this is still more work than simply comparing two numbers.
How do you find the difference of two fractions with the same denominator?
Subtract as if there were no denominators.
What are the two fractions when you add them together equal 1?
There are an infinite number of correct answers.The two fractions areany number/any denominatorandthe same denominator minus the first number/the same denominator
A denominator that is the same in two or more fractions?
A "common denominator"

What is the denominator in the same in two or more fractions?
That's a common denominator.
When two or more fractions have the same denominator it is called what?
Common denominator
Denominator that is the same in two or more fractions?
That's a "common" denominator. "Common" means "same for both" or "same for all".

What are like denominators?
That means that two or more fractions have the SAME denominator.

What is the same about two fractions that are like fraction?
They have the same denominators.
What is a wy to compare two fractions when the denominator are the same?
They are in the same order, by size, as their numerators.
How do you add two fractions with the same denominator?
numerators you add, denominators you leave it the same
