Finding the Least Common Denominator (LCD)

To find the least common denominator (LCD) for fractions, we need to find the smallest number that is divisible by all the denominators involved. Let's find the LCD for each pair of fractions you provided:

1. For 2/9 and 5/6: - The denominators are 9 and 6. - The LCD is the smallest number that is divisible by both 9 and 6. - The LCD for 9 and 6 is 18. - Therefore, the LCD for 2/9 and 5/6 is 18.

2. For 5/12 and 7/8: - The denominators are 12 and 8. - The LCD is the smallest number that is divisible by both 12 and 8. - The LCD for 12 and 8 is 24. - Therefore, the LCD for 5/12 and 7/8 is 24.

3. For 5/6 and 7/12: - The denominators are 6 and 12. - The LCD is the smallest number that is divisible by both 6 and 12. - The LCD for 6 and 12 is 12. - Therefore, the LCD for 5/6 and 7/12 is 12.

4. For 3/26 and 9/13: - The denominators are 26 and 13. - The LCD is the smallest number that is divisible by both 26 and 13. - The LCD for 26 and 13 is 26. - Therefore, the LCD for 3/26 and 9/13 is 26.

5. For 2/8 and 6/7: - The denominators are 8 and 7. - The LCD is the smallest number that is divisible by both 8 and 7. - The LCD for 8 and 7 is 56. - Therefore, the LCD for 2/8 and 6/7 is 56.

6. For 14/17 and 3/4: - The denominators are 17 and 4. - The LCD is the smallest number that is divisible by both 17 and 4. - The LCD for 17 and 4 is 68. - Therefore, the LCD for 14/17 and 3/4 is 68.

7. For 7/12 and 8/15: - The denominators are 12 and 15. - The LCD is the smallest number that is divisible by both 12 and 15. - The LCD for 12 and 15 is 60. - Therefore, the LCD for 7/12 and 8/15 is 60.

8. For 3/8 and 5/6: - The denominators are 8 and 6. - The LCD is the smallest number that is divisible by both 8 and 6. - The LCD for 8 and 6 is 24. - Therefore, the LCD for 3/8 and 5/6 is 24.

9. For 7/18 and 8/15: - The denominators are 18 and 15. - The LCD is the smallest number that is divisible by both 18 and 15. - The LCD for 18 and 15 is 90. - Therefore, the LCD for 7/18 and 8/15 is 90.

10. For 8/15 and 9/10: - The denominators are 15 and 10. - The LCD is the smallest number that is divisible by both 15 and 10. - The LCD for 15 and 10 is 30. - Therefore, the LCD for 8/15 and 9/10 is 30.

Summary of Least Common Denominators (LCDs):

1. The LCD for 2/9 and 5/6 is 18. 2. The LCD for 5/12 and 7/8 is 24. 3. The LCD for 5/6 and 7/12 is 12. 4. The LCD for 3/26 and 9/13 is 26. 5. The LCD for 2/8 and 6/7 is 56. 6. The LCD for 14/17 and 3/4 is 68. 7. The LCD for 7/12 and 8/15 is 60. 8. The LCD for 3/8 and 5/6 is 24. 9. The LCD for 7/18 and 8/15 is 90. 10. The LCD for 8/15 and 9/10 is 30.
