Easy way to subtract two fractions with unlike denominators to determine the difference

The video tutorial covers adding and subtracting fractions with unlike denominators. It explains the concept of the least common denominator (LCD) and how to find it by multiplying denominators. The tutorial provides examples to illustrate when multiplying denominators gives the correct LCD and when it does not. It then demonstrates how to apply the LCD to perform fraction operations, ensuring equivalent equations by multiplying both the numerator and denominator. The tutorial concludes with a final calculation example, showing how to subtract fractions with a common denominator.
