When two or more fractions have the same denominator, it means they have a common base for their fractional parts. This allows for easier comparison and addition or subtraction of the fractions, as the denominators are already aligned. By having the same denominator, the fractions can be easily manipulated by adding or subtracting the numerators while keeping the denominator constant. This simplifies operations involving fractions with common denominators.

Can you call 2 equivalent fraction like fractions?
No. Like fractions have the same denominator.
Why do you need a common denominator?
Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.
What is the the value of -1 as denominator?
-1 as a denominator changes the sign of the fractions. 1/-2 is the same as -(1/2).
What are like fractions?
Fractions with the same denominators are called like fractions. eg: 2/5 and 4/5 eg: 6/7and 9/7
If 2 fractions have the same numerator but different denominator how can you tell which is greater?
In that case, and assuming both fractions are positive, the one with the larger denominator is the smaller fraction, because you are dividing by a larger number.
