Studying rational expressions is crucial because they are fundamental in algebra and are used to model and solve real-world problems involving ratios and rates. Understanding how to manipulate and simplify these expressions enhances critical thinking and problem-solving skills. Additionally, rational expressions form the basis for more advanced topics in mathematics, including calculus and functions, making them essential for further studies in science, engineering, and economics.
