Sal adds 19 3/18 + 18 2/3 by rewriting each mixed number to have a common denominator.

Demonstrates how to add two mixed numbers by adding the whole numbers separately and then finding the least common denominator for the fractions and adding those. The sum of the fractions is then simplified. [2:20]

Demonstrates how to add two mixed numbers, where the fractions have the same denominator, by adding the whole numbers together and then the fractions. [1:34]
