Understand Mixed Numbers

A mixed number combines a whole number and a proper fraction, such as 2 3/4 (two and three-quarters). An improper fraction has a numerator that is greater than or equal to its denominator, such as 11/4. Both forms represent the same amount — you can convert freely between them.
