An improper fraction is a type of fraction where the numerator (the top number) is larger than or equal to the denominator (the bottom number). This means that the fraction represents a value greater than or equal to one whole.
For example, in the fraction

.
Understanding improper fractions is important for solving problems that involve fractions greater than or equal to one.
