Using Fraction Models to Determine Equivalent Fractions

Oct 13, 2025 by wbrum.org 146 views

Introduction

In mathematics, equivalent fractions are fractions that have the same value, even though they may look different. For example, the fractions 1/2 and 2/4 are equivalent because they represent the same amount of a whole. In this article, we will explore how to use fraction models to determine if two fractions are equivalent or not. We will examine a set of fractions and choose whether each pair is equivalent or not equivalent.

What are Equivalent Fractions?

Equivalent fractions are fractions that have the same value, but may have different numerators and denominators. For example, the fractions 1/2 and 2/4 are equivalent because they represent the same amount of a whole. To determine if two fractions are equivalent, we need to find a common denominator and compare the numerators.

Using Fraction Models to Determine Equivalent Fractions

Fraction models are visual representations of fractions that can help us understand and compare fractions. A fraction model is a diagram that shows a part of a whole. For example, the fraction 1/2 can be represented by a diagram with one half of a circle shaded.

To determine if two fractions are equivalent using fraction models, we need to create a diagram for each fraction and compare them. If the diagrams are the same, then the fractions are equivalent.

Examining the Fractions

Let's examine the following fractions and determine if they are equivalent or not equivalent:

Fractions	Equivalent?
$\frac{2}{3}$
$\frac{4}{6}$

$\frac{2}{3}$ and $\frac{4}{6}$

To determine if these fractions are equivalent, we need to create a diagram for each fraction and compare them.

Step 1: Create a Diagram for $\frac{2}{3}$

To create a diagram for $\frac{2}{3}$ , we need to divide a circle into three equal parts and shade two of them.

+---------------+
|             |
|  2/3        |
|  ********** |
|  ********** |
|  ********** |
+---------------+

Step 2: Create a Diagram for $\frac{4}{6}$

To create a diagram for $\frac{4}{6}$ , we need to divide a circle into six equal parts and shade four of them.

+---------------+
|             |
|  4/6        |
|  ********** |
|  ********** |
|  ********** |
|  ********** |
|  ********** |
+---------------+

Step 3: Compare the Diagrams

Now that we have created diagrams for both fractions, we can compare them. If the diagrams are the same, then the fractions are equivalent.

In this case, the diagrams are not the same. The diagram for $\frac{2}{3}$ has two shaded parts, while the diagram for $\frac{4}{6}$ has four shaded parts. Therefore, the fractions $\frac{2}{3}$ and $\frac{4}{6}$ are not equivalent.

Conclusion

In this article, we have explored how to use fraction models to determine if two fractions are equivalent or not. We have examined a set of fractions and chosen whether each pair is equivalent or not equivalent. By creating diagrams for each fraction and comparing them, we can determine if the fractions are equivalent or not.
