Finding the common denominator so you can add two fractions

The video tutorial explains how to handle fractions with like and unlike denominators. It begins by discussing the simplicity of adding fractions with common denominators. The tutorial then addresses the challenge of unlike denominators and introduces the concept of the least common denominator (LCD). It explains how to convert fractions to have a common denominator by finding the LCD and adjusting the numerators and denominators accordingly. Finally, it demonstrates how to add fractions once they have common denominators, resulting in the correct answer.

Explain how 5/20 is equivalent to 1/4.

What is the final answer when adding the fractions after finding a common denominator?
