PLZ HELP ME!!!!!!!!!!

OpenStudy (rainbow_rocks03):

OpenStudy (anonymous):

Well the first one is simple, what did we do to find the percentage every time?

OpenStudy (rainbow_rocks03):

ummm

OpenStudy (anonymous):

Just imagine n as the result

OpenStudy (rainbow_rocks03):

im sorry its just i cant think anymore right no, i have been working on school sense 7:30 in the morning

OpenStudy (rainbow_rocks03):

*now

OpenStudy (anonymous):

Do you just want the answers, or do you want me to continue explaining?

OpenStudy (rainbow_rocks03):

Im trying though, and yes plz explain

OpenStudy (rainbow_rocks03):

I THINK if you explain it will help a little

OpenStudy (anonymous):

k so how much is 73% actually?

OpenStudy (rainbow_rocks03):

73% = 0.73

OpenStudy (anonymous):

yup and then what did we do? with the .73?

OpenStudy (rainbow_rocks03):

multiply?

OpenStudy (rainbow_rocks03):

Brill, my brain is really fried right now >.<

OpenStudy (anonymous):

YUP thats right

OpenStudy (anonymous):

So you would multiply 215 and .73!

OpenStudy (rainbow_rocks03):

0.73 * 215 = 156.95

OpenStudy (anonymous):

Yeah but you dont need the answer, the first question is only asking HOW to get to the answer

OpenStudy (anonymous):

So look for one that says .73*215

OpenStudy (rainbow_rocks03):

so my answer would be the second choice

OpenStudy (rainbow_rocks03):

right?

OpenStudy (anonymous):

Yeah :D

OpenStudy (rainbow_rocks03):

now onto #2

OpenStudy (anonymous):

Ok so a percent is basically a decimal right?

OpenStudy (anonymous):

So like 40% is .40

OpenStudy (anonymous):

So what is that as afraction

OpenStudy (rainbow_rocks03):

.40 as a fraction?

OpenStudy (rainbow_rocks03):

4/100 ?

OpenStudy (rainbow_rocks03):

btw I have the answer for #3

OpenStudy (anonymous):

No 4/100 is .04, try a little higher

OpenStudy (rainbow_rocks03):

also here are the ones after #3

OpenStudy (rainbow_rocks03):

umm, idk

OpenStudy (anonymous):

so .40 in letter form is 40 hundreths

OpenStudy (anonymous):

so what is that as a fraction

OpenStudy (rainbow_rocks03):

40/100

OpenStudy (anonymous):

Yeah :D

OpenStudy (anonymous):

So apply that to #2

OpenStudy (rainbow_rocks03):

my answer is 23/94 = n/100

OpenStudy (anonymous):

YUP

OpenStudy (rainbow_rocks03):

ok

OpenStudy (rainbow_rocks03):

onto #4

OpenStudy (anonymous):

So what did you get as an answer for the last one on that one

OpenStudy (rainbow_rocks03):

the answer I got for #3 was 34

OpenStudy (anonymous):

Ok so you've been using what we've been talking about which is good

OpenStudy (anonymous):

but thats wrong sorry

OpenStudy (rainbow_rocks03):

oh, it is?

OpenStudy (anonymous):

Now it's telling you that 85 is 40% OF something

OpenStudy (anonymous):

So you cant multiply there

OpenStudy (rainbow_rocks03):

I searched on google also and 14 people said that is the answer

OpenStudy (anonymous):

Ok so set up the equation here or the ratio or whatever

OpenStudy (study312):

rainbow I commented on the other post, did you already answer it all?

OpenStudy (rainbow_rocks03):

well 4 people said thats the answer and 14 people agreed that it is the answer

OpenStudy (rainbow_rocks03):

no I havent answered it all

OpenStudy (rainbow_rocks03):

I had more thats why

OpenStudy (anonymous):

\[\frac{ 85 }{ n }=\frac{ 40 }{ 100 }\]

OpenStudy (anonymous):

Thats what it is asking

OpenStudy (study312):

ok well you can check back to see my comment. I am done for the day so see ya, good luck.

OpenStudy (rainbow_rocks03):

thx

OpenStudy (anonymous):

Yeah rainbow sorry but I rechecked the wording too they're wrong

OpenStudy (anonymous):

Try solving for n in what I gave you

OpenStudy (rainbow_rocks03):

ugh I just need #4 #5 #6 #7 and #8

OpenStudy (rainbow_rocks03):

im so tired

OpenStudy (rainbow_rocks03):

n * 40 = 40n and 85 * 100 = 8500

OpenStudy (anonymous):

so 8500=40n

OpenStudy (anonymous):

8500/40= 212.5 and that is correct

OpenStudy (rainbow_rocks03):

ok

OpenStudy (rainbow_rocks03):

#4 next

OpenStudy (anonymous):

It's asking to take the percentage, so just multiply

OpenStudy (rainbow_rocks03):

answer to #4 & #5

OpenStudy (anonymous):

Do you want it?

OpenStudy (rainbow_rocks03):

so I can just solve 6 7 & 8 because I HAVE to solve those :p and yes plz

OpenStudy (anonymous):

K

OpenStudy (anonymous):

Number 4 is 62.5

OpenStudy (anonymous):

And 5 is 265.614375

OpenStudy (anonymous):

Round and stuff ofcourse

OpenStudy (rainbow_rocks03):

this is #6

OpenStudy (anonymous):

Ok so for the proportion set it up like I set up #3 earlier

OpenStudy (anonymous):

But substituting the right number

OpenStudy (rainbow_rocks03):

I made it smaller

OpenStudy (anonymous):

OR do you just want an answer?

OpenStudy (rainbow_rocks03):

I just need the equation on how to solve it

OpenStudy (rainbow_rocks03):

So I can see how to solve it

OpenStudy (anonymous):

Ok so the proportion to solve it is \[\frac{ 108 }{ x }=\frac{ 36 }{ 100 }\]

OpenStudy (anonymous):

Thats it

OpenStudy (rainbow_rocks03):

I just cross multiply them right?

OpenStudy (anonymous):

yeah and then isolate the variable and stuff after

OpenStudy (rainbow_rocks03):

ok, just making sure

OpenStudy (rainbow_rocks03):

I forget how to isolate the variable sometimes

OpenStudy (rainbow_rocks03):

can you type it out?

OpenStudy (anonymous):

Ok so what did you get after you cross multiplied?

OpenStudy (rainbow_rocks03):

I got 10800 & 100n

OpenStudy (anonymous):

Uhh shouldnt be 100n

OpenStudy (rainbow_rocks03):

oh

OpenStudy (rainbow_rocks03):

I am REALLY frustrated right now!

OpenStudy (anonymous):

Look at the cross multiplying, n is across from 36 not 100

OpenStudy (rainbow_rocks03):

oh
