$$

Introduction

Simplifying algebraic expressions is a crucial skill in mathematics, and it is essential to understand the rules and techniques involved in simplifying expressions. In this article, we will focus on simplifying the given expression $\frac{2ab - 4b}{2ab}$ using various techniques and rules. We will break down the expression into smaller parts, identify common factors, and use algebraic properties to simplify it.

Understanding the Expression

The given expression is $\frac{2ab - 4b}{2ab}$. To simplify this expression, we need to understand the rules of algebra and the properties of fractions. The expression consists of two parts: the numerator and the denominator. The numerator is $2ab - 4b$, and the denominator is $2ab$.

Factoring the Numerator

To simplify the expression, we can start by factoring the numerator. The numerator is $2ab - 4b$, and we can factor out the common term $2b$. This gives us:

$$\frac{2ab - 4b}{2ab} = \frac{2b(a - 2)}{2ab}$$

Canceling Common Factors

Now that we have factored the numerator, we can cancel out common factors between the numerator and the denominator. The numerator is $2b(a - 2)$, and the denominator is $2ab$. We can cancel out the common factor $2b$ from both the numerator and the denominator. This gives us:

$$\frac{2b(a - 2)}{2ab} = \frac{a - 2}{a}$$

Simplifying the Expression

Now that we have canceled out the common factors, we can simplify the expression further. The expression is now $\frac{a - 2}{a}$. We can simplify this expression by dividing both the numerator and the denominator by $a$. This gives us:

$$\frac{a - 2}{a} = 1 - \frac{2}{a}$$

Conclusion

In this article, we simplified the expression $\frac{2ab - 4b}{2ab}$ using various techniques and rules. We factored the numerator, canceled out common factors, and simplified the expression further. The final simplified expression is $1 - \frac{2}{a}$. This expression is a simplified form of the original expression, and it is a crucial step in solving algebraic equations.
