1. Translating Problems into Equations
Chapter 1
Section 1.7

2. Objective
Students will translate simple word problems into equations

3. Concept
A word problem describes a situation in which certain numbers are related to each other. Some of these numbers are given in the problem and are considered to be known numbers. Other numbers are at first unknown. You must determine their values by using the facts of the problem.

4. Concept
Simple word problems often give two facts involving two unknowns. The following steps can be used to translate such problems into equations. You do not have to solve the problem

5. Concept
Remember that how many things/people are discussed in the word problem, that is how many variables you need in your equation

6. Concept Steps to writing equations Read the problem carefully
Choose a variable to represent the unknowns
Reread the problem and write an equation

7. Example Translate the problem into an equation
Marta has twice as much money as Heidi
Together they have $36
How much money does each have?

8. Example Translate the problem into an equation
A wooden rod 60 in. long is sawed into two pieces
One piece is 4 in. longer than the other
What are the lengths of the pieces?

9. Example Translate the problem into an equation
There are 22 students in a classroom
There are 12 more girls than boys
Find the number of boys in the classroom

10. Example
Translate the problem into an equation The perimeter of a rectangle is 36 cm. The length is twice as long as the width. Find the width of the rectangle.
