Manny and Susan have an egg carton full of eggs to use for their science project.
Manny uses 1/3 of the eggs and Susan uses 1/2 of the eggs. Which fraction of the eggs
did Manny and Susan use for their project?

You'd find the LCM (lowest common denominator) which is 6. First, we'll take 1/3 which the denominator becomes 6. You see one side has been basically multiplied by 2, so you'd do it to both sides, giving us 2/6. Next, we do the same thing with 1/2. 2 -> 6 1 -> 3. 3/6. So finally, we have 3/6 + 2/6, which is 5/6.
