How can i reduce 9/18 i'm having hard times with math and i really need

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! :)
