The document provides steps for subtracting fractions and mixed numbers with like denominators. It shows examples of subtracting fractions and mixed numbers step-by-step, emphasizing the need to rename mixed numbers so the fractions being subtracted have the same denominator before performing the subtraction. Key skills needed include renaming mixed numbers by "breaking the whole number into __ + 1" and identifying the denominator to use.
