Finding the Common Denominator for Fractions

To find the common denominator for each pair of fractions, we can follow a simple process. First, we need to find the least common multiple (LCM) of the denominators of the fractions. Then, we can use the LCM as the common denominator for the fractions.

1. Finding the Common Denominator for 6/15 and 11/18: - The denominators are 15 and 18. - The LCM of 15 and 18 is 90. - Therefore, the common denominator for 6/15 and 11/18 is 90.

2. Finding the Common Denominator for 4/15 and 3/20: - The denominators are 15 and 20. - The LCM of 15 and 20 is 60. - Therefore, the common denominator for 4/15 and 3/20 is 60.

3. Finding the Common Denominator for 2/77 and 3/44: - The denominators are 77 and 44. - The LCM of 77 and 44 is 3388. - Therefore, the common denominator for 2/77 and 3/44 is 3388.

4. Finding the Common Denominator for 4/49 and 5/63: - The denominators are 49 and 63. - The LCM of 49 and 63 is 441. - Therefore, the common denominator for 4/49 and 5/63 is 441.

5. Finding the Common Denominator for 5/16 and 5/12: - The denominators are 16 and 12. - The LCM of 16 and 12 is 48. - Therefore, the common denominator for 5/16 and 5/12 is 48.

6. Finding the Common Denominator for 5/121 and 8/99: - The denominators are 121 and 99. - The LCM of 121 and 99 is 11979. - Therefore, the common denominator for 5/121 and 8/99 is 11979.

7. Finding the Common Denominator for 1/51 and 1/68: - The denominators are 51 and 68. - The LCM of 51 and 68 is 1734. - Therefore, the common denominator for 1/51 and 1/68 is 1734.

8. Finding the Common Denominator for 15/98 and 13/72: - The denominators are 98 and 72. - The LCM of 98 and 72 is 3528. - Therefore, the common denominator for 15/98 and 13/72 is 3528.
