Modeling Subtraction of Fractions with Unlike Denominators

The video tutorial teaches how to solve word problems involving the subtraction of fractions with unlike denominators by using visual models. It emphasizes the importance of not subtracting numerators and denominators directly and provides examples to illustrate the correct method. The tutorial includes two example problems: one involving paint and another involving a flower, demonstrating how to use models to find the solution.
