Convert from Mixed: Learn

Fractions consist of two numbers. The top number is called the numerator. The bottom number is called the denominator.

denominator

An improper fraction is a fraction that has a numerator larger than or equal to its denominator. A proper fraction is a fraction with the numerator smaller than the denominator.

A mixed number consists of an integer followed by a proper fraction.

Example: The mixed number, three and three-fifths, can be changed to an improper fraction by converting the integer portion to a fraction with the same denominator as the fractional portion and then adding the two fractions. In this case the integer portion (3) is converted to fifteen-fifths. The sum of the two fractions becomes 15/5 + 3/5 = 18/5.
