It defines mixed numbers as having a whole number part and fractional part, and improper fractions as fractions where the numerator is larger than the denominator. The document then provides step-by-step instructions for converting a mixed number to an improper fraction by multiplying the whole number by the denominator and adding the numerator, and for converting an improper fraction to a mixed number by dividing the numerator by the denominator and writing the remainder over the denominator. Several examples are worked through.
