Adding Fractions and Radicals

Dr. K from Infinite Magic Productions explains how to add a fraction and a radical. The tutorial begins with an example of adding one quarter and radical x. The radical is converted into a fraction with the same denominator by multiplying it by 4/4. This allows the two to be added together, resulting in the final answer of (4 radical x + 1) divided by 4.
