Math tutorial video for adding two fractions with unlike denominators

The video tutorial explains how to add and subtract fractions with unlike denominators by finding the least common denominator (LCD). It covers the process of determining the LCD, multiplying both the numerator and denominator to create equivalent fractions, and finally adding the fractions once they have a common denominator.

Why is it important to multiply both the numerator and denominator by the same value when changing fractions?
