WORD PROBLEM SOLVING USING RATIONAL EQUATIONS
How Do You Solve a Word Problem with a Rational Equation
This tutorial provides a great real world application of math! This tutorial shows you how to take the information given in a word problem and turn it into a rational equation. Then, you'll see how to solve that equation and get your answer!
Solving Rational Equations & Word Problems - ThatTutorGuy
Solving Rational Equations (x's in denominators) This video pertains to finding common denominators when said denominators contain x's, x 2 's, and other factorable junk. With the aforementioned common denominators established, one is heretofore then able to perform the solving-related work for hire.
WORD PROBLEMS WITH RATIONAL EQUATIONS
WORD PROBLEMS WITH RATIONAL EQUATIONS. We solve the equation by mumultplying every term by 6x (the LCM) and clearing fractins to get 3x + 2x = 6. Solving the equation we get that x = 6/5 of an hour or one hour and 12 minutes. Note that it makes sense that the two together will complete the job in a shorter amount of time than either working alone.

Rational Functions, Equations and Inequalities. The easiest way to solve rational inequalities algebraically is using the sign chart method, which we saw here in the Quadratic Inequalities Section Method. A sign chart or sign pattern is simply a number line that is [PDF]
Motion – Rational Equations - MyMathClasses
Solve the Equation. Using the method taught by your instructor, solve the equation for the variable. Keep in mind when solving a Motion -- Rational Equations problem, you may get two solutions to the equation. If one of these solutions is negative, eliminate it because a rate (speed) cannot be negative.
"Work" Word Problems | Purplemath
As you can see in the above example, "work" problems commonly create rational equations. But the equations themselves are usually pretty simple to solve. One pipe can fill a pool 1 times as fast as a second pipe. When both pipes are opened, they fill the pool in five hours.[PDF]
