                      Unit fractions                               Proper fractions
                      Fractions with numerator 1 are called unit   Fractions in which the numerator is less than        M1_L3
                      fractions.                                   the denominator are called proper fractions.















                      Improper fractions                           Mixed fractions
                      Fractions in which the numerator is more     Mixed fractions consist of a whole number
                      than or equal to the denominator are called   along with a proper fraction.
                      improper fractions.
