Finding the Least Common Denominator for Fractions

To find the least common denominator (LCD) for the fractions 20/7 and 12/5, we can follow a specific process. The LCD is the smallest multiple that both denominators share. Let's calculate the LCD for each pair of fractions.

1. LCD for 20/7 and 12/5: - The denominators are 7 and 5. - The least common multiple (LCM) of 7 and 5 is 35. - Therefore, the least common denominator for 20/7 and 12/5 is 35.

2. LCD for 24/11 and 30/1: - The denominators are 11 and 1. - The least common multiple (LCM) of 11 and 1 is 11. - Therefore, the least common denominator for 24/11 and 30/1 is 11.

These calculations provide us with the least common denominators for the given fractions.
