4 is a multiple of 1?

Yes, it's another GRE question. Got this question today: If p, q, and r are positive integers such that q is a factor of r, and r is a multiple of p, which of the following must be an integer? They give several answer choices. In the explanation, they choose r=4, q=2, and p=1. I thought when you multiply a given whole number by any other whole number, the result is a multiple of that number. I'm stumped on what number multiplied by 4 results in 1. Is this another Kaplan goof?

1 x 4 = 4, so doesn't think make 4 a multiple of one? In fact, anything can be a multiple of one, since it would just be 1 x itself? Correct me if I'm wrong, anyone 🙂

this is what i was thinking. it fits the definition when you compare it to other numbers. i think anything can be a multiple of 1

Uh, yeah, all positive integers are multiples of 1.

For r and p, r is a multiple of p if r = xp for an integer x. In this case, x=4.

The way you're thinking about it is p = xr, or is 1 a multiple of 4. That is not what the question is asking.

Also choose your wording carefully so that you get in the right mindset. The number (but not integer) 1/4 multiplied by 4 is equal to 1. 😉

I think you've got it backwards.

"4 is a multiple of 1"

means 1 x Y = 4 (where Y=4 in this case)

I think you're interpreting it as 4 x Y = 1. The multiple is the bigger number.

No test prep book is going to prepare you that well if you don't know and understand basic concepts. I'm sorry if that seems harsh but it's the truth.

ive also written this in other GRE threads. i'm a firm believer that you have to know the basics if you want to score high in quantitative. and it takes a long time to relearn what you may have forgotten after SOO many yrs. It seems stupid, but i spent a large amt of time practicing my basics before i even started the real problems. And whenever i did a problem and knew i was slow or didnt fully understand, i would go back and practice the basic math that was in that question. It is the only way to finish the problems as fast as you can and still be accurate in your math

I understand the basic concepts, thank you very much. I got a 760 Q the last time I took this test - in '96. It's the wording that got me. Defined, a multiple is the product of any quantity and an integer. So, r is the product of p and x, as breenie pointed out. Thank you. This is what happens when I stay up for 23 hours waiting for a flight to come in so I can collect and secure 4 computers, then go home and sleep for 4 hours only to do it all again. I'm surprised I'm doing as well on the practice tests as I am.

Actually I'm the one who pointed it out in those exact terms. But everyone said the same concept...

All your score from '96 tells me is that you understood the concepts in 1996. That was a long time ago. It's not really outside of the realm of possibility that you need a refresher on them - take it easy.

I'm a non-trad, too. When I took the GRE during college the first time I blew the quant out of the water.

When I started with practice tests this time, well, let's just say I was very, very rusty. The basic GRE books didn't really help me much. Like others have suggested, I had to go back and study geometry and trig review books. It all came back pretty quickly, but that was a vital step in my GRE studying. I ended up doing fine, but still not as well as I did when high school math was fresh.

The GRE quant is very much designed for people who have had high school-level math recently. Since that's probably not going to change, we non-trads have to take a different approach to studying. It's not something we need to be ashamed or defensive about, just something of which we need to be aware.

Yes, you pointed them out, but in the same terms as the book. Breenie gets the credit for changing it around a bit and making it pop out. 🙂

I think my issue is that prior to studying for GRE, I was studying concepts such as calculating the Equivalent Air Depth of normoxic and hypoxic trimix gasses. When the old brain gets focused on ppO2 and max operating depth, definitions from 2nd grade don't come to back to life as quickly. Once I got some sleep, it became quite clear that they are saying q and p are factors of r.

 

[Risika]

Don't feel bad, I got a B.S. in Mathematics (recently) and wording still gets me sometimes. As long as you understand the concepts (which, if you're rusty - definitely do some reviewing) then don't worry too much. Just make sure to get a good night's sleep before the test and try to (I know it's hard sometimes) read the questions more carefully and/or more than once.

Prior to reading your post, I was using Bayesian inference and maximum likelihood estimation to analyze effects in a genetic model for catnip response in a 3,000 cat pedigree. I still read only the thread title and knew what it was saying rather than assuming it was an error in the book. 🙂

I guess what I'm saying is why don't you just look it up next time.

If we all wanted to play like that, that could be the response to about half the posts on here.

The question was asked and answered, and you've made it blindingly clear you knew the answer before anybody else. Geez, would you like a cookie or something? 🙂

I guess what I'm saying is why don't you just drop it?

 

[cheeto]

Good post Lunajett. I agree. I think this forumn is a great resource that can be used to help each other out. Sometimes it just takes a fresh perspective on a problem to find a solution! If the question seems below you when reading it then do not answer it because I am sure there are lots of people who are more then happy to respond!

Any post that can be responded to by "Why don't you look it up yourself?" is not really a very worthwhile post. Just sayin...

That's not really my intent. Rather - the point is that everyone knew the answer, because it is a question that he could just look up himself and know the answer to (and probably learn about the why better that way too...) rather than soliciting opinions or advice which I think is really the value of this forum...

I'm afraid you'd poison the cookie, to be honest. Weren't you going to put me on ignore or something?

 

[rileydog]

I think the reason for posting was to get a different perspective on the question. Looking it up might not help. Sometimes you need to have something explained in a different way than a teacher or a book does to understand it. I think breenie's explanation did that and was more helpful and of more value to this thread than other posts.

 

[nyanko]

lol I don't really care whose answer is ~most helpful~ and I doubt breenie or anyone else posts for that reason either...it's not a competition, jeez.

Personally I just tend to be blunt about pointing things out and don't hold back. If people have issues with that, they can feel free to ignore the posts. But if someone responds to me, I'm going to answer it.

Was just trying to say that your post about the value of the forum made it seem like the OP had no value or should not have been asked because it was something that, in your opinion, could have been looked up.

 

[breenie]

Uhhh... glad I could help? 🙂

 

[BlacKAT33]

How about using only one thread to answer GRE questions instead of making multiple ones? that way it is all condensed and whoever wants to answer or ignore the thread can.

It may have been a silly Q but i know when iw as studying for the GREs i asked a TON of silly Qs to my kaplan teacher haha sometimes rules&numbers get all jumbled when you have been doing many questions for a long period. It was something that could have been looked up online, but yea so are about half the posts on here. I'd like to think of it as since we are a close group of friends it is more like asking friends than just posting randomly on the forum. and Armymutt has been around for a while so at least it wasn't some new person who is just using us

👍 You are much better at explaining things than I am. 🙂

I had considered this idea a few months ago, but the threads kept growing with extra info. You'd have to weigh through a bunch of posts to find an answer to your question. Perhaps someone with an in depth knowledge of the board's functions could create a consolidated lead post that links to questions within the thread. Otherwise, it becomes an jumbled mess of questions and answers that isn't very helpful if you're looking for a quick solution.

There is a difference between being blunt and tactfully candid. The latter is best practiced when dealing with people you don't know on a personal level, i.e. you share DNA (minds out of the gutter, please [though it stands true for that as well]) or you have assisted them to the toilet after an evening of intense fun. In a profession where you are dealing with clients, bluntness is not the best way to go about it. I struggle with this issue, as extreme bluntness has been the order of the day for me for the past 10 years. Neither really bothers me, especially on an effectively anonymous message board.

If you say so.

And yet you've posted six times (so far) in it. If it's so beneath you, why not just ignore it rather than going out of your way to ridicule the OP?

I'm afraid you'd poison the cookie, to be honest.

I would never do that to a good cookie, I LOVE cookies! 🙂

Right, the medium and audience are important considerations IMO.

Here we are not dealing with clients. I don't talk to any of you (or anyone in my life, really) like I would talk to a client in general were I dealing with one in a professional situation.

lunajett: I was in some way pointing out that I did try to post constructively along with my crankiness, not really saying that anyone's answer was better than anyone else's! You're absolutely right in that there is value in trying to approach things from different angles and get people's perspectives on them. I guess where we differ is that for me, if I were unsure about the answer to this particular question when coming across it in a book, the first thing I would think is "oh crap I must not understand this concept properly" and I'd go to whatever lengths I needed to in order to understand it on my own. For me, this is more of a question that has a pretty concrete answer. Probably a function of different learning styles and such. WHICH of course is a fun conversation all on its own, but man is this thread derailed from multiples. 😀

And as far as why not just ignore it...well, I could ask the same of you regarding my posts. 😉

I like that you're all getting a lot more offended by my posts than even the OP did.

I'm desensitized to it, as I am to a lot of things. It's not necessarily the best way to go through life, but it keeps me sane.
