How are proper and improper fractions alike?

Proper and improper fractions are alike in that they both represent parts of a whole. Both types of fractions have a numerator (the top number) and a denominator (the bottom number). The relationship between the numerator and denominator determines the value of the fraction. The main difference between proper and improper fractions is that in a proper fraction, the numerator is smaller than the denominator, while in an improper fraction, the numerator is equal to or larger than the denominator.
