The video tutorial explains how to add fractions by finding a common denominator, preferably the least common denominator. It demonstrates creating equivalent fractions by multiplying both the numerator and denominator by the same number. The tutorial walks through an example of adding fractions and discusses simplifying the result by checking for common factors. The process of determining if a fraction can be simplified is also covered, emphasizing the importance of identifying even numbers and other common divisors.
