Grade 5 - Fractions - Add or Subtract with Unlike Denominators find LCM and LCD

This video explains how to add fractions with different denominators by finding the least common denominator (LCD). The process involves organizing the multiples of each denominator to identify the smallest shared multiple, which becomes the common denominator. The fractions are then adjusted by multiplying both the numerator and denominator to match the LCD, allowing for straightforward addition.

This method helps students understand the importance of working with the same unit when adding or subtracting fractions.
