Introduction

Fractions are a fundamental concept in mathematics, and understanding equivalent fractions is crucial for solving various mathematical problems. In this article, we will explore the concept of equivalent fractions, learn how to write equivalent fractions, and provide examples to illustrate the concept.

What are Equivalent Fractions?

Equivalent fractions are fractions that have the same value, but differ in their numerator and denominator. In other words, two fractions are equivalent if they can be simplified to the same value. For example, $\frac{1}{2}$ and $\frac{2}{4}$ are equivalent fractions because they can be simplified to the same value.

Writing Equivalent Fractions

To write equivalent fractions, we need to multiply or divide the numerator and denominator by the same number. Let's consider the following examples:

1. Writing a Fraction Equivalent to $\frac{3}{5}$

To write a fraction equivalent to $\frac{3}{5}$ , we can multiply both the numerator and denominator by 2. This gives us:

\frac{3}{5}=\frac{6}{10}

2. Writing Two Fractions Equivalent to 12

To write two fractions equivalent to 12, we can divide 12 by 2 and 3. This gives us:

\frac{12}{2}=\frac{24}{4}

\frac{12}{3}=\frac{36}{6}

Using Area Models or Fraction Strips to Solve Problems

For questions 3-10, we will use area models or fraction strips to solve each problem.

3. $\frac{3}{5}=\frac{6}{10}$

To solve this problem, we can use an area model or fraction strips. Let's consider the area model:

	3/5	6/10
5	3	6
10	6	12

As we can see, the two fractions have the same value, which is 3/5.

4. $\frac{1}{2}=\frac{2}{4}$

To solve this problem, we can use an area model or fraction strips. Let's consider the area model:

	1/2	2/4
2	1	2
4	2	4

As we can see, the two fractions have the same value, which is 1/2.

Conclusion

In conclusion, equivalent fractions are fractions that have the same value, but differ in their numerator and denominator. To write equivalent fractions, we need to multiply or divide the numerator and denominator by the same number. We can use area models or fraction strips to solve problems involving equivalent fractions. By understanding equivalent fractions, we can solve various mathematical problems and develop a deeper understanding of fractions.
