Question

Which number can be used as a common denominator for the fractions 1/4 and 5/6
?

Answer 1

Answer:

There is an infinite number of common denominators, but 12 is the least common denominator.  You could also use any other number that is a multiple of 12, such as 24, 36, and 48.

Explanation:

12 is the least common denominator because it is the smallest number that is a multiple of both 4 and 6.

$4*3=12$

$6*2=12$

You can also use any other multiples of 12 because they are all multiples of 4 and 6.
