This is a bit tricky, but you'll think it's easy once you get used to it!

Let's try this:

1/2 + 1/3

The main rule of this game is that we can't do anything until the denominators are the same!

We need to find something called the least common denominator (LCD)... It's really just the LCM of our denominators, 2 and 3.

The LCM of 2 and 3 is 6. So, our LCD 6.

We need to make this our new denominator...

Change the 1/2:

Change the 1/3:

1/2 + 1/3 = 3/6 + 2/6

Now we can do it!

(3+2)/6 = 5/6
