This video tutorial explains two methods for subtracting fractions with unlike denominators. The first method involves listing common multiples to find a common denominator, demonstrated with examples of subtracting 3/6 and 1/4, and 6/9 and 2/6. The second method uses multiplication of denominators to find a common denominator, again illustrated with the same examples. The video emphasizes the importance of choosing the lowest common multiple for simplicity.
