Changing Mixed Numbers to Improper Fractions

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

      numerator  
    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, 3 3/5, 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 15/5. The sum of the two fractions becomes 15/5  +  3/5  =   18/5.

The entire conversion is:
3/5  =   15/5  +  3/5  =   18/5.
