please help i have a test tuesday how do u find percent for a question l

Percent is the number you're looking for divided by the total, multiplied by 100.

E.g.
1. Percent of students who passed given 50 out of 100 passed an exam is given by (50/100)*100 = 50%

2. Percent of answers a particular student got right out of a total of 50 questions, given that student got 20 of them right is given by (20/50)*100 = 40%

Is that okay for you?
 
I totally agree Denis! XD

The student council (if you have one) can raise that request.

\(\displaystyle >>\)Because, they often say that, for example, 50/100 gives 0.5, not 50%. \(\displaystyle < < \)

I have never witnessed this before. /\ /\

Unknown008,

no, percents are not calculated as what you have typed.

-----------------------------------------------------------------------------

\(\displaystyle \text{Percent is the number you're looking for divided by the total, }\)
\(\displaystyle multiplied \ by \ 100 \%.}\)

E.g.
1. Percent of students who passed given 50 out of 100 passed an exam is given by

\(\displaystyle (50/100)*100 \% = 50 \%.\)

2. Percent of answers a particular student got right out of a total of 50 questions,
given that student got 20 of them right is given by

\(\displaystyle (20/50)*100\% = 40\%.\)

-------------------------------------------------------

\(\displaystyle 100\% \ = \ 1\)


\(\displaystyle \dfrac{50}{100} \ \ \text{equals} \ \ 50 \%\)


When a number (fraction or otherwise) is multiplied by 100%,
the value is unchanged.


When a number is multiplied by 100, the value is multiplied by 100.


So, (50/100)*100 = \(\displaystyle \dfrac{50}{100}\bigg(\dfrac{100}{1}\bigg) \ = \ 50, \ not \ 50 \%.\)

Because, they often say that, for example, 50/100 gives 0.5, not 50%. And from
there, they will get 0.5% instead.

As long as the "method" you are referring to includes the "%" sign as I have used it.

\(\displaystyle But,\) if you mean the "method" you showed in your earlier post, such as
your example of (50/100)*100 = 50%, then that is wrong, and it is wrong to show
that to someone else as if it's the correct way.

The value is unchanged, right, that's why the 100% is there, because that actually means 1 and one times a fraction keeps the original fraction.

It is a method that I found to be effective when trying to make someone understand. Because, they often say that, for example, 50/100 gives 0.5, not 50%. And from there, they will get 0.5% instead.

It's just like using units, where % is the unit there.


Also, yes, most of the time, I pass for a stranger ;P
 
Hm.. it could be that I have been lurking on this forum since like 2007 and know all of you here :p

But nope, it was a username I started to use and generally use the same through many site I use, except where it's already taken then I might use UnknownOO8 (youtube and Deviant Art), or Unknown008_ (twitter)
 
Oh, I haven't seen the two posts in this page... sorry about that >.<

But no, I haven't uploaded any vid on youtube yet, dunno what to upload XD

And of course that would have been unknown to you, I'm apparently very skilled at that ;)

Then how do you know that they are there? ;)

Just kidding. What I find interesting is that this thread appears all on one page, for me.

Now I am wondering why the number of pages in a thread would be specific to each viewer.
 
The settings! I forgot to set them to 20 posts per page, which I usually do on forums where I plan to get some activity :roll:
