How to Eliminate Fractions in Algebra Equations

Algebra is can be useful in financial calculations.

Syracuse University defines algebra as a field of mathematics that utilizes symbols and equations to examine the relationship between two or more things that can change over time. Fractions and symbols are often used in equations, and you often need to find the value of one or more symbols in the equation before it can be solved. The unknown quantity is often referred to as "x." Eliminating fractions from algebraic equations can simplify the process of solving them, especially when a calculator is used.

Things You'll Need

• Calculator

Instructions

1. Divide the top number of a fraction (the numerator) by the bottom number (the denominator) to convert the fraction to a decimal. This makes algebraic equations simpler to process when using a calculator.

2. Replace the fraction with the decimal number in the equation since they have the same value.

3. Repeat this process for each fraction until they have all been replaced by decimal numbers. You can then go about solving the equation.

Tips & Warnings

• Multiply the denominators of the fractions to determine the lowest common denominator. You can then multiply both sides of the equation by that number as another way of removing fractions from the equation.
