Introduction

Simplifying complex fractions is an essential skill in mathematics, particularly in algebra and calculus. It involves breaking down intricate expressions into simpler forms, making them easier to work with and understand. In this article, we will focus on simplifying the given complex fraction: $\frac{\frac{3}{x}}{3-\frac{4}{x}}$ . We will use various techniques and strategies to simplify this expression, making it more manageable and revealing its underlying structure.

Understanding the Complex Fraction

The given complex fraction is $\frac{\frac{3}{x}}{3-\frac{4}{x}}$ . To simplify this expression, we need to understand its components. The numerator is $\frac{3}{x}$ , and the denominator is $3-\frac{4}{x}$ . Our goal is to simplify this fraction by finding a common denominator or using other algebraic techniques.

Simplifying the Complex Fraction

To simplify the complex fraction, we can start by multiplying the numerator and denominator by the reciprocal of the denominator. This will eliminate the fraction in the denominator and make it easier to simplify.

$\frac{\frac{3}{x}}{3-\frac{4}{x}} = \frac{\frac{3}{x} \cdot \frac{x}{x}}{3-\frac{4}{x} \cdot \frac{x}{x}}$

Simplifying the expression, we get:

$\frac{\frac{3}{x} \cdot \frac{x}{x}}{3-\frac{4}{x} \cdot \frac{x}{x}} = \frac{\frac{3}{x} \cdot 1}{3-\frac{4}{x} \cdot 1}$

Using the Distributive Property

Now, we can use the distributive property to simplify the expression further.

$\frac{\frac{3}{x} \cdot 1}{3-\frac{4}{x} \cdot 1} = \frac{\frac{3}{x}}{3-\frac{4}{x}}$

Finding a Common Denominator

To simplify the expression, we need to find a common denominator for the numerator and denominator. The common denominator is $x$ , so we can rewrite the expression as:

$\frac{\frac{3}{x}}{3-\frac{4}{x}} = \frac{\frac{3}{x}}{\frac{3x-4}{x}}$

Simplifying the Expression

Now, we can simplify the expression by dividing the numerator and denominator by $x$ .

$\frac{\frac{3}{x}}{\frac{3x-4}{x}} = \frac{3}{3x-4}$

Conclusion

In this article, we simplified the complex fraction $\frac{\frac{3}{x}}{3-\frac{4}{x}}$ using various techniques and strategies. We started by multiplying the numerator and denominator by the reciprocal of the denominator, then used the distributive property to simplify the expression further. Finally, we found a common denominator and simplified the expression by dividing the numerator and denominator by $x$ . The simplified expression is $\frac{3}{3x-4}$ .
