Now the denominators are different, so you have to find the least common denominator (Look at Julie's post for more info on LCD). To do that you do these steps.
Steps
Step 1: Find the lowest multiple of both denominators. (In this case, find the lowest multiple of 2 and 6)
Step 2: Multiply the numerators by the same number you multiplied the denominator by. (In this case, 6x2= 12 and 2x6=12, so for 1/2, 1x6=6 and for 3/6 it's 3x2=6)
Step 3: Add as you usually would.

OK, I'll use a picture example for each step. Maybe that will help...I hope.

So, yah. That's how you add fractions. Well, I'm spent and done. Note me if I did anything wrong or if I made a mistake or should fix it in anyway. Thankies!
