Introduction

In mathematics, simplifying complex fractions is a crucial skill that helps in solving various mathematical problems. A complex fraction is a fraction that contains one or more fractions in its numerator or denominator. In this article, we will focus on simplifying a complex fraction using Method II. This method involves multiplying both the numerator and the denominator by the conjugate of the denominator to eliminate the complex numbers.

What is a Complex Fraction?

A complex fraction is a fraction that contains one or more fractions in its numerator or denominator. For example, $\frac{\frac{1}{2}}{\frac{3}{4}}$ is a complex fraction. Simplifying complex fractions can be challenging, but with the right approach, it can be done easily.

Method II for Simplifying Complex Fractions

Method II for simplifying complex fractions involves multiplying both the numerator and the denominator by the conjugate of the denominator. The conjugate of a complex number is obtained by changing the sign of the imaginary part. For example, the conjugate of $3+4i$ is $3-4i$ .

Step 1: Identify the Complex Fraction

The given complex fraction is $\frac{-6}{\frac{6w}{w-1} - 4}$ . To simplify this fraction, we need to identify the complex numbers in the numerator and the denominator.
