To add fractions with a common denominator, you simply add the numerators and keep the denominators the same. For instance, 1/7+3/7 = 4/7
If the denominators are different, you will need to find an equivalent fraction of one of the values that means the denominators can be equal. This is done by multiplying top and bottom of a fraction by the same amount. For instance, if we had 1/3 + 4/9, we would need to multiply top and bottom of the first fraction by 3. That gives us 3/9 + 4/9. Then the addition can be completed normally.
What else can I help you with?
How do you solve fractions?
You cannot solve fractions. There may be sums or products containing fractions or equations that can be solved. But fractions themselves cannot.
How is adding fractions like adding whole numbers?
adding fractions is like adding a WHOLE lot of parts of numbers
What are the rules for adding fractions?
Ensure that the denominators are the same when adding or subtracting fractions.
How are adding fractions different?
When adding or subtracting fractions their denominators must be the same
How do you solve proper fractions?
You cannot solve proper fractions. You may be able to solve problems involving fractions but that is NOT the same thing. Furthermore, the solution methods depend on the problem.
How do you solve a fraction problem when you don't have the same denominator?
If you are adding or subtracting unlike fractions, convert them to equivalent fractions with a common denominator.
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.
When is it useful to find the least common multiple and greatest common factor of two or more numbers to solve a problem?
When you are simplifying fractions or adding and subtracting unlike fractions.

When is it useful to find the LCM or GCF of two numbers to solve a problem?
When adding or subtracting fractions with different denominators and when reducing fractions to their lowest termsWhen adding or subtracting fractions with different denominators their lowest common multiple is needed and when reducing fractions to their lowest terms their greatest common factor is needed.

How is adding mixed numbers the same as adding fractions?
Mixed numbers can be converted to improper fractions. Then, it is exactly the same as adding proper ones.
