Here are the essential concepts you must grasp in order to answer the question correctly.
Complex Fractions
A complex fraction is a fraction where the numerator, the denominator, or both contain fractions themselves. To simplify complex fractions, one typically finds a common denominator for the inner fractions and rewrites the complex fraction as a single fraction. This process often involves algebraic manipulation to eliminate the nested fractions.

Common Denominator
A common denominator is a shared multiple of the denominators of two or more fractions. When simplifying complex fractions, finding a common denominator allows for the combination of fractions into a single fraction, making it easier to perform operations such as addition, subtraction, or simplification. In the context of the given question, identifying the common denominators of the inner fractions is crucial.

Algebraic Manipulation
Algebraic manipulation involves rearranging and simplifying expressions using algebraic rules. This includes operations such as factoring, distributing, and combining like terms. In the context of simplifying the complex fraction, algebraic manipulation is essential for transforming the expression into a more manageable form, ultimately leading to the simplified result.
