How do I find the (LCM) or the (LCD) of fraction?

Is the LCM the same as the LCD?

Do they have a link with each other?

To find the lowest common multiple, you multiply up. For example, 2/4 and 1/3...Take 4x1 is 4, 4 x 2 is 8, 4 x 3 is 12..Then, multiple up with 3. 3 x1 is 3, 3x 2 is 6, 3 x 3 is 9, 3 x 4 is 12. The lowest common multiple is 12. It is also the common denominator when adding the problem.
