Complete The Fraction That Is Equivalent To $\frac{1}{2}$.$\frac{1}{2} = \frac{3}{\square}$

Introduction

Fractions are a fundamental concept in mathematics, and understanding equivalent fractions is crucial for solving various mathematical problems. In this article, we will focus on solving equivalent fractions, specifically the fraction $\frac{1}{2}$, which is equivalent to $\frac{3}{\square}$. We will break down the problem step by step and provide a clear explanation of the solution.

What are Equivalent Fractions?

Equivalent fractions are fractions that have the same value, but with different numerators and denominators. 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.

The Problem: $\frac{1}{2} = \frac{3}{\square}$

The problem states that $\frac{1}{2}$ is equivalent to $\frac{3}{\square}$. To solve this problem, we need to find the value of the missing denominator, denoted by $\square$. We can start by setting up an equation:

$$\frac{1}{2} = \frac{3}{\square}$$

Step 1: Cross-Multiplication

To solve for the missing denominator, we can use cross-multiplication. Cross-multiplication involves multiplying the numerator of one fraction by the denominator of the other fraction, and vice versa. In this case, we can multiply the numerator of the first fraction ($1$) by the denominator of the second fraction ($\square$), and vice versa.

$$1 \times \square = 3 \times 2$$

Step 2: Simplifying the Equation

Now that we have the equation $1 \times \square = 3 \times 2$, we can simplify it by multiplying the numbers.

$$\square = 6$$

Conclusion

In conclusion, the missing denominator in the equivalent fraction $\frac{1}{2} = \frac{3}{\square}$ is $6$. Therefore, the equivalent fraction is $\frac{3}{6}$.
