What is a common denometer?
When adding or subtracting fractions with different denominators, it is necessary to find a common denominator to solve the equation. A common denominator is like a common multiple, except its function is as the bottom number in a fraction.
Why do you have to have a common denominator?
A common denominator is needed when adding or subtracting fractions of different denominators.
How do you solve all fractions problems?
You basically have to learn separately how to do different things with fractions, including finding a common denominator; converting fractions to a different denominator; simplifying fractions; adding and subtracting fractions; multiplying fractions; dividing fractions.
How do you minnous fractions?
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

How do you explain the steps of a fraction equation by adding?
First find a common denominator. Then, add the numerators together. Simplify if possible.
What is the rule of adding and subtracting different denominator?
Find the lowest common denominator by finding the lowest common multiple of the denominators
What common denominator would you use to add fractions?
There isn't a universal answer to all problems. What you should try to do is find the lowest common denominator between the fractions you are adding.
What do you subtract when you have two rational expressions that have a common denominator?
When subtracting you have to make sure that the second numerator is multiplied by -1 so the equation turns into adding. When you add and you already have a common denominator you add the numerators and leave the denominator the same.
Do you have to have the same denominator when you subtract fractions?
Yes, but the numerator is different,same as adding fractions
When adding or subtracting fractions do you have to have the numerator the same or denominator?
The denominators must be the same, the numerators can be different.
Adding three fractions with different denominator?
2/3+1/6+3/4=
How is adding fractions like adding whole numbers... How is it different?
Similarities: the sum does not depend on which number you start with (distributive)Differences: you must find a common denominator for the fractions (whole numbers have a common denominator [1]
