►TEAS Prep Course - https://www.mometrix.com/university/t... ►http://www.flashcardsecrets.com/teas/ We have provided five TEAS practice test questions for the TEAS Test Version 5. These questions are specific to the TEAS and are designed to help you in preparing for your test. ►TEAS Transcript: On the TEAS test, you are going to encounter a lot of word problems. Here we have one example of something you might see when taking the TEAS test. It says, "If Sara can read fifteen pages in ten minutes, how long will it take her to read forty-five pages?" Here we have a rate: fifteen pages in ten minutes. Which can be written as a ratio, or a fraction. Fifteen pages in ten minutes. Or, you can write it in the reverse: ten minutes in fifteen pages, or ten minutes to fifteen pages. Then we have this third piece of information: forty-five pages. And you see that the units there, the pages, match the units, or one of the units you have in your first ratio. That needs to be a clue to use a proportion, which is just a ratio that's equal to a ratio. And what's really important about setting up proportions, is that you're consistent. So if your first ratio is pages to minutes, then your second ratio should also be pages to minutes, which tells us to put the forty-five pages on top of our fraction in our numerator. So what were trying to find is, how many minutes is it going to take to read those forty-five pages. There is more than one way to solve a proportion. One of the easier ways, and it won't always work because the easier ways don't always work or we wouldn't come up with the harder ways. One of the easier ways to solve this would be: to look at either the numerator or the denominator, and figure out what you'd have to do to get your other numerator. For example, what do you have to do to fifteen pages to get forty-five pages? Well fifteen times three is forty-five. So you just do the same thing in your denominator. Ten times three would be thirty minutes. So it's going to take thirty minutes to read those forty-five pages. But like I said, that won't always work. What will always work, is using cross-products. And that just means cross-multiplying. Fifteen times "x" is "15x". And that is equal to ten times forty-five, which is four hundred fifty. What you need to know about proportions is that, their cross products are always equal. So now you just need to solve your equation, which means undoing what's been done to your variable "x". So in this case, we need to divide both sides by fifteen. And "x", again equals thirty. So now we know it's going to take thirty minutes to read those forty-five pages. #mometrixtestprep #mometrixteas #teas #teasexam #teastest #teasreview #teasprep #teaspractice #teasstudy #teaspracticetest
