Introduction

In mathematics, solving for a variable in an equation is a fundamental concept that is used extensively in various mathematical operations. One of the most common types of equations is the fraction equation, where the variable is part of a fraction. In this article, we will focus on solving for $n$ in a simple fraction equation, specifically the equation $\frac{n}{7} = \frac{10}{7}$.

Understanding the Equation

The given equation is $\frac{n}{7} = \frac{10}{7}$. This equation states that the ratio of $n$ to $7$ is equal to the ratio of $10$ to $7$. To solve for $n$, we need to isolate the variable $n$ on one side of the equation.

Step 1: Multiply Both Sides by 7

To eliminate the fraction, we can multiply both sides of the equation by $7$. This will cancel out the denominator on both sides, leaving us with a simple equation.

$\frac{n}{7} \cdot 7 = \frac{10}{7} \cdot 7$

This simplifies to:

$n = 10$

Step 2: Verify the Solution

To verify that our solution is correct, we can substitute $n = 10$ back into the original equation and check if it is true.

$\frac{10}{7} = \frac{10}{7}$

This is indeed true, so we can confirm that $n = 10$ is the correct solution.

Conclusion

Solving for $n$ in a simple fraction equation like $\frac{n}{7} = \frac{10}{7}$ is a straightforward process that involves multiplying both sides by the denominator to eliminate the fraction. By following these steps, we can easily solve for the variable $n$ and verify our solution.
