Question

Find the lcd of 2/3 and 1/3

Answer 1

2/3 and 1/3 already have the same denominator (3), so the LCD is 3.

We could immediately combine 2/3 and 1/3, obtaining 3/3, or 1.

Answer 2

Hello!

The least common denominator is like the least common multiple. As you can see, these numbers already have the same denominators, and cannot be divided any further as they are prime. 

Therefore, our answer is 3.

I hope this helps!
