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.
Step 2
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, …
Here, the least common multiple of 9 and 12 is 36.
Thus, least common denominator (LCD) of 4/9 and 5/12 is 36.
