Adding Mixed Numbers with the same Denominator

Mixed numbers consist of an integer followed by a fraction.

How to add two mixed numbers whose fractions have the same denominator:
• Add the numerators of the two fractions
• Place that sum over the common denominator.
• If this fraction is improper (numerator larger than or equal to the denominator) then convert it to a mixed number
• Add the integer portions of the two mixed numbers
• If adding the fractional parts created a mixed number then add its integer portion to the sum.
