How to Add Fractions With Variables

Adding fractions and variables is simple when you follow the proper steps.

Adding fractions with variables is a bit challenging, but some challenges can be good when understanding how to do algebra. As long as you follow the process to solving the equation, you will be successful. Here are the steps on how to add fractions with variables.

Instructions

Adding Fractions and Variables

1. Before you begin to solve a math equation, you must understand how to do algebra by working with fractions and variables to find common denominators. First, examine your equation to be solved. If your denominators are not equal, you will need to find a way to make them the same so you can add easily.

2. Determine the least common denominator (LCD) in this problem. It is the lowest number that both denominators can be divided into. In this case, it is 10.

3. Change the denominator of the number that is not 10. To do that you would have to multiply by two. Be sure to also multiply the numerator by two as well.

4. You are almost ready to add. Remember that the sole X in your equation is 1X. You may want to put a one next to that X so that you do not forget.

5. Add your numerators. Since both variables are X, you move the X next to your new numerator, and also transfer your denominator to the new fraction.

6. Reduce your fraction if necessary.
