Subtracting Mixed Numbers and Fractions

This video tutorial teaches how to subtract fractions and mixed numbers by decomposing them into smaller parts. It begins with a review of equivalent fractions and explains how whole numbers can be decomposed into fractions. The tutorial addresses common misunderstandings and uses practical examples, such as a cookie scenario and a fraction bar model, to illustrate the subtraction process. The lesson concludes with examples of subtracting mixed numbers, emphasizing the importance of decomposition in solving these problems.
