What is the least common denominator of 3/8 and 5/11

Answer 1

To find the least common denominator (LCD) of 3/8 and 5/11, we need to determine the smallest common multiple of the denominators, which are 8 and 11.

To find the least common multiple (LCM), we can list the multiples of both numbers until we find a common multiple.

Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, ...

Multiples of 11: 11, 22, 33, 44, 55, 66, 77, 88, ...

The first common multiple we encounter is 88. Therefore, the least common denominator of 3/8 and 5/11 is 88.

Answer 2

Answer: 88

Explanation:

To find the least common denominator, we will list multiples of 8 and 11. We will then find the smallest number that both lists share.

8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88

11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121

We see that the least common denominator is 88.
