Description

"Applications of Fractional Equations" PPT courseware

Summary:

Steps and methods for solving word problems using fractional equations:

1. Review, set up, list, explain, test, answer

2. Find the equivalent relationship

Summary

General steps and precautions for solving word problems using fractional equations:

(1) Review the question: Find out the meaning of the question and the known and unknown quantities in the question, and find out the equivalence relationship that expresses the full meaning of the question.

(2) Assume the unknowns: If the unknowns are set directly, then ask what to set. If the unknowns are set indirectly, then use the algebraic expression containing the unknown to express the relevant unknowns.

(3) Find the equivalent relationship and list the equations.

(4) Solving equations: the process can be saved

(5) Inspection:

① Check whether the obtained solution is the solution of the listed equation.

② Check whether it meets the meaning of the question

(6) Write the answer: Don’t forget the name of the unit.

What did you learn?

1. Experience the process of using fractional equations to solve practical problems and further enhance your application awareness.

2. By solving practical problems, understand how to properly grasp different forms of equivalence relationships.
