How do you add fractions with variables?
Variables As Part of the Fraction Since both of these fractions have what’s called a common denominator, we can just add the numerator. Common denominators allow for fractions to be added when the terms on bottom are the same. Since both fraction have x on the bottom, we can simply add 5 and 3 on top.
How do you add two fractions with different denominators and variables?
Here’s the traditional way to add fractions with two different denominators:
- Find the LCM of the two denominators. Suppose you want to add the fractions 3/4 + 7/10.
- Increase the terms of each fraction so that the denominator of each equals the LCM.
- Substitute these two new fractions for the original ones and add.

How do you add fractions in an equation?
To add fractions follow these steps:
- Find the least common denominator.
- Change each fraction to an equivalent fraction having the LCD as its denominator.
- Add the numerators and place over the LCD.
- Simplify or reduce the answer.
How do you solve fractions with multiple variables?
Solve equations by clearing the Denominators
- Find the least common denominator of all the fractions in the equation.
- Multiply both sides of the equation by that LCD.
- Isolate the variable terms on one side, and the constant terms on the other side.
- Simplify both sides.
Can you multiply variables with different exponents?
When you multiply two numbers or variables with the same base, you simply add the exponents. When you multiply expressions with different bases and different exponents, there is no rule to simplify the process.
