Download as KEY, PDF0 likes481 views
The document provides examples and steps for subtracting fractions and mixed numbers with like denominators. It demonstrates renaming mixed numbers by breaking them into whole numbers and fractions. The key steps are to break the mixed numbers into whole numbers and fractions, identify the denominator which becomes the new denominator, and then subtract the fractions and whole numbers separately.
