Hey!

LCD stands for Lowest Common Denominator.
----------------------------------------------------------------------
Step-by-step explanation:
So let's say we have the equation 1/9 * 16/27
We want to find the LCD of both fractions. To find the LCD of both fractions find a the lowest common denominator in both fractions.
In this equation the lowest common denominator is 27 because 9 can go in 27 and 27 can go into itself. Se basically 27 is the lowest possibly common denominator both fractions can get to.
