Step 1
Consider the given fraction 4/9 and 5/12.
The least common multiple of the denominators is called the least common denominator.
To find the least common denominator (LCD), first determine list the multiples of each denominator.

Now, find the multiple of 9 and 12.
Multiples of 9: 9, 18, 27, 36, 45, 54, …
Multiples of 12: 12, 24, 36, 48, 60, …
