Learn vocabulary, terms, and more with flashcards, games, and other study tools. 1. Recall that you can solve equations containing fractions by using the least common denominator of all the fractions in the equation. Multiplying each side of the equation by the common denominator eliminates the fractions. This method can also be used with rational equations. Rational equations are equations containing rational expressions. 2. Steps For Solving Real World Problems. Highlight the important information in the problem that will help write two equations. Define your variables; Write two equations; Use one of the methods for solving systems of equations to solve. Check your answers by substituting your ordered pair into the original equations. 1.

Common Core: 6.EE.7 Aug 01, 2018 · In Grade 8, writing one-variable equations or inequalities with variables on both sides that represent problems using rational number coefficients and constants as well as writing a corresponding real-world problem when given a one-variable equation or inequality with variables on both sides of the equal sign using rational number coefficients ... One method for solving rational equations is to rewrite the rational expressions in terms of a common denominator. Then, since you know the numerators are equal, you can solve for the variable. To illustrate this, let’s look at a very simple equation. Since the denominator of each expression is the same, the numerators must be equivalent.
