You landed on this page because you entered a search term similar to this: convert decimal to fraction - formula.We have an extensive database of resources on convert decimal to fraction - formula. Below is one of them. If you need further help, please take a look at our software "Algebrator", a software program that can solve any algebra problem you enter!  
If you need help in preparing for the math part of the GREgeneraltest, you have come to the right place.  Note that you do not haveto be a student at WTAMU tousethis study session.  It was created as a service to anyone whoneedshelp getting ready for this test.

If this is your first visit to our website, please read the disclaimer.

The math part of the GRE General Test is split into four mainareas:



Below are the specific concepts you need to know about each of thoseareas.  This list was compiled from researching the MathReview for Practicing to Take the GRE General Test (youneedacrobat Reader to download)  webpage at the official GREwebsite created by the Educational Testing Services.

Under each specific concept, you will find links to in-depthtutorialsthat will help learn and review the material.  These tutorialscomefrom the WTAMU Virtual Math Lab, which Icreated.  Within these tutorials, you will find pertinentdefinitions,formulas, step-by-step explanations, an answer/discussion section withstep-by-step solutions, and links to other credible webpages that canhelpyou further with that topic.

In math, when you study a specific topic, a lot of times youare incorporatingother mathematical topics into solving the problem.  Some of thetutorialswill overlap each other.  This will help reinforce the conceptsyouneed to know for the GRE.


 

HOW TO EFFECTIVELYUSE THISWEBPAGE:
 
 
Under the areas,you need to go to all the links that are under each topic togetthe full benefit. 

Under the algebra area,there is a lotof overlapping between the different levels (beginning, intermediate,andcollege) of tutorials.  Find the algebra level that agreeswithyou most and do all of the tutorials under that level.  If youstart below college level algebra, make sure that you make your wayup through college algebra before you take the GRE general test.

Arithmetic

 
 
The first area that we will be looking at isarithmetic.  Youknow, fun things like making sure you have the negative in the rightplaceand remembering when you have to find the common denominator of yourfractions. Don't worry, I have the utmost confidence that youwill do much better with arithmetic than Calvin.

Algebra

 
It's back!!!!!!   Just when you thought itwas safe to comeback to school, POW, another math test with ALGEBRA!!!  I'm hopingthat with this section of tutorials, Iwill convert some of you who are math atheists (you know who you are).

SPECIALNOTE: 
Note that most of the topics under Algebra contain tutorials from threelevels (lowest to highest): beginning, intermediate, and college. 

Ideally, for the Algebra section, you want to be ableto work thecollege level by the time you take the GRE test. 

There will be some overlapping between the levels. If a topichas tutorials in more than one level, try going under the highest levelfirst.  If that is too hard for you, go to the tutorials of thenextlevel down, if available.  If that is too hard for you, go to thetutorials of the next level down, if available. 

Once you find a level to start with, make sure thatif it is belowcollege level, in the end you work your way up to college algebra. 

The beauty of this is it is individualized. You can goat your own pace at the comfort of your own computer.  Youknowbetter than anyone else what your algebra skills are.
