• How do we compare them if there is so many?!?
• do the same thing on the number line.you just need more time
• which one is greater between 4/3 and 2/5?
• Hint: One of them is greater than a whole, and one of them isn't. With this, you'll be able to tell which one's greater from there!

• what is x+y=16? why is x equal to y?
• What you have here is an example of algebra!

Letters represent values that are unknown.
Generally, in algebra, you want to solve for x. That means you want to get x all alone.

Whatever you do to one side of the equal sign, you must do to the other side to keep it the same. So, x=16-y because you can subtract y from each side of the equation to get x by itself.

It isn't a given that x and y are equal. But if they are, you can switch the y for another x as such, x+x=16. What number added to itself equals 16? Figure that out and there you have it, you found x!

Hope this helps!
