How to convert word problems into algebraic equations
This article explains some of those relationships.
Translating Word Problems into Equations
I was asked, I need an easy and helpful way to teach writing equations. Example: Helen has 2 inches of hair cut off each time she goes to the hair salon. If h equals the length of hair before she cuts it and c equals the length of hair after she cuts it, which equation would you use to find the length of Helen's hair after she visit the hair salon?
We can have objects that Travel at Different Ratesobjects that Travel in Different Directions or we may need to find the distance Given the Total Time Fraction Problems involve fractions or parts of a whole. Geometry Word Problems deal with geometric figures and angles described in words. This include geometry word problems Involving PerimetersInvolving Areas and Involving Angles Integer Problems involve numerical representations of word problems. Lever Problems deal with the lever principle described in word problems. Mixture Problems involve items or quantities of different values that are mixed together. Step 6: Answer the question in the problem The problem asks us to find how many hours Karen needs to work.
The length of a rectangular map is 15 inches and the perimeter is 50 inches. Find the width. The width of a rectangle. Step 2: Assign a variable for the width. We know the length is 15 inches. We also know the perimeter is 50 inches. Perimeter is the distance all the way around a figure. Since length is 15 inches, width is w, and perimeter is 50, we get Step 5: Solve the equation. Step 6: Answer the question in the problem. The problem asks us to find the width of a rectangle.
How words and phrases translate into math
The width of the rectangle is 10 inches. Find the radius of the face. The radius of the face of a circular clock. Step 2: Assign a variable for the radius.
First we need to know a formula that will relate circumference and radius since those are two pieces of information in the problem. The formula for the circumference is. We are told that the circumference is Three times the radius translates into 3r. Now we need to add We now have two expressions for circumference. Now we can set up the equation Step 5: Solve the equation. In some classes your teacher may want you to leave in its exact form rather than approximating the value as 3. We will use the how to convert word problems into algebraic equations here. If your teacher wants you to leave as part of your answer, you should ask how to do that. Step 6: Answer the question in the problem The problem asks us to find the radius of the clock face.
The radius of the clock face is 4 centimeters. Examples If 4 is subtracted from twice a number, the result is 10 less than the number. What is your answer? Last year Betty the cow gave gallons less than twice the amount from Bessie the cow. Together, Betty and Bessie produced gallons of milk. How many gallons did each cow give? Twice a number is added to the number and the answer is Solve the equation using good algebra techniques.
Examples of converting word problems into mathematical expressions and equations
Even if you know the answer right away, using algebra will better prepare you to solve problems that do not have obvious answers. Write the equation. Multiply both sides by 2. Check the answer in the problem and make sure it makes sense. Step 7. Answer the question with a complete sentence. Problem-Solving Strategy Read the word problem. It may be helpful to first restate the problem in one sentence before translating.
What you’ll learn to do: Write and solve equations from word problems
Check the answer in the problem. Make sure it makes sense.
