Why do we have to do so much work? Scholars learn how to set up bar models to represent a situation involving work. They use these bar models to help set up equations with rational coefficients to solve the problem situation.

Scholars first learn to solve two-step equations with fractional coefficients and constants by traditional methods and by clearing the denominator. They continue by learning another approach to solve two-step equations that have decimal...

Time to study the most sensible function — rational functions! The seven-lesson unit develops the concept of a rational function through a connection to rational numbers and fractions. Scholars graph functions, solve equations, and...

It only takes the denominator to be zero to make an expression undefined. A video resource makes the connection of undefined fractions to rational expressions. It points out that to determine when a rational expression is undefined, you...

Work out to Algebra II with the 50-question worksheet that practices different types of functions. Multiple choice questions focus on topics such as rational, radical, and logarithmic functions. The resource comes with a printed answer...

Jam packed with problems, this advanced Algebra worksheet focuses on topics such as domain, solving quadratics, solving rationals, and function notation.  

Groups explore illumination with NASA's Lighting Environment Test Facility (LETF) as a context. Using the TI-Nspire app, groups determine the lux equation that models their simulation. They then use the lux equation to solve problems...

Got a fraction in your equation? Don't like that fraction? Just multiply both sides by the reciprocal of that fraction to get rid of it. Now you can solve the problem using the steps necessary to isolate your variable. Don't forget to...

Translate a word problem into a rational equation. This word problem might cause some to pause and ponder, and some to just give up and skip the problem altogether. It does involve some fractions, so watch this video and get a better...

What is a rational expression? Is it something to do with numerators, denominators, and polynomials? What things make up a rational equation? Watch this video as the teacher explains what makes a rational equation.

When you have a hole in a graph it means that both the numerator and denominator equaled 0 in an equation. So what does that mean? Learners can brush up on this graphing concept and feel OK when they realize a hole in a graph is just a...

In this college level mathematics worksheet, students solve rational equations and identify the extraneous solutions.  The two page worksheet contains fifty-eight problems.  Answers are included. 

Use the least common denominator to solve rational equations with variables in the denominators of algebraic fractions. Learners can watch this video to find out how to do just this! An instructor solves 2 problems by finding the least...

A comprehensive video, this resource explains how to solve an equation when you have a variable in the denominator. The lecturer works through 2 different problems that represent 2 situations. From this video, pupils can gain knowledge...

In this algebra worksheet, learners solve rational equations including two application problems. This worksheet contains explanations to aid in understanding. 

In this Algebra I worksheet, students solve rational equations that may have extraneous solutions.  The worksheet is two pages and contains twenty problems.  Answer key is provided. 

For this rational equations worksheet, students solve 20 rational equations.  Students find the zeros of rational functions and solve rational equations.

In this rational equation worksheet, students solve 20 equations with a variable in the denominator of one more terms. They also read real-life application problems, write a rational equation to fit the problem and solve the equation....

Algebra learners explore the concept of writing equations using rational expressions. This work sheet contains a number of word problems including reciprocal number problems, work problems, and problems can that be solved using...

For this word problem worksheet, algebra students solve classic work problems. They find work rates, time to complete a task with a partner, or time to complete task alone. Twelve word problems are included in this worksheet. An answer...

Equations with algebraic fractions still require the LCD. Pupils learn to solve equations with algebraic fractions. Multiplying through by a common denominator gives a simpler equation that they can solve.

Viewers of this short video examine abstract equations with fractional expressions and learn to find a least common multiple to eliminate denominators. They then see how to manipulate the equation to isolate the variable of interest.

There are a lot of steps in this problem. But just like walking up a flight of stairs, you should take one step at a time, so too in the solving of this problem. The instructor explains each step and what to do to move to the next one.
