The document defines improper fractions and mixed numbers, and provides examples for converting between the two forms. Specifically, it explains that an improper fraction has a numerator greater than the denominator, and can be converted to a mixed number by determining how many whole parts there are. Students are given examples like 6/3 = 2, 10/3 = 3 1/3, and instructed to complete practice problems converting improper fractions to mixed numbers.
