First, find the greatest common factor of the numerator and denominator. ... It's 9. ... Divide the numerator and denominator by their greatest common factor. ... You're left with 1/2 ... 9/18 reduced to lowest terms.
This may actually be easier than you think. Once I explain it to you, you'll get it! :)

So, you have the fraction 9/18, right? To reduce means to bring to the simplest form possible. Therefore, you must find the number that can go into both of these numbers. 

Now, since 9 is a factor of both itself and 18, that is what you will divide both numbers by. 

9 divided by 9 is one and 18 divided by 9 is two. When you put them both together again, you have a final answer of one half. 

Now, this might sound a bit complicated depending on where you are in math and the way that you figure out problems, but I assure you that it is much easier than it sounds! :)

Now try one of your own. Try these problems and work them out:
7/14   6/18   5/25   and   4/20

If you are having more trouble and cannot figure this process out, you may want to consider going to a teacher, educated adult, or a math tutoring place such as mathnasium. I'm sure that you can figure it out, though!

Thanks for the opportunity to answer your question and I hope this helps! :) If you liked my answer and it helped, then I would kindly ask you to consider making this answer the brainiest answer. I am very close to the next level and only need the brainiest answers! :)
