I would start by expressing each as a fraction over 100 and reducing to get closer to finding the least common multiple of the denominators
anonymous
  • anonymous
so total must be divisible by

ENGLISH PEOPLE ENGLISH

tons is right

is anybody good at java programming

In english what he said means?
anonymous
  • anonymous
12/100= 3/25
anonymous
  • anonymous
12 out of 100 is 6 out of 50 or 3 out of 25
anonymous
  • anonymous
WHERE R U GETTING THESE NUMBERS
anonymous
  • anonymous
while 14 out of 100 is 7 out of 50 and can't be reduced any further
anonymous
  • anonymous
percent means out of 100
anonymous
  • anonymous
...so 12% = 12 out of 100 or 12/100 which reduces like a fraction to 6/50 and 3/25
anonymous
  • anonymous
28/100=7/25
anonymous
  • anonymous
.30=3/10
anonymous
  • anonymous
ya so the minimum ammount of people is 10?
anonymous
  • anonymous
.16=4/25
anonymous
  • anonymous
ok so we want a number that is divisible by all those denominators
anonymous
  • anonymous
Im not good with m,ath but i can rock your orld with any other subject >.<
anonymous
  • anonymous
So, if you look at all of them, they all can be out of 100, obviously, but there is a smaller number that they all can be out of
anonymous
  • anonymous
can they all be expressed as a whole number out of 25 by reducing like in the process above?
anonymous
  • anonymous
Uhhh
anonymous
  • anonymous
or rather
anonymous
  • anonymous
idk...?
anonymous
  • anonymous
like 12% = 12/100 = 3/25, can they all go to out of 25?
anonymous
  • anonymous
multiply all the denominators
anonymous
  • anonymous
SO MANY WORDS... its like a mathbook
anonymous
  • anonymous
im not sure if they can
anonymous
  • anonymous
I am using "like" and "out of", do you want help or the answer
anonymous
  • anonymous
Help What do you mean by "Like"
anonymous
  • anonymous
for instance
anonymous
  • anonymous
so the smallest number sampled possibly is 25*50*25*10*25
anonymous
  • anonymous
We're not on facebook.... lol
anonymous
  • anonymous
tonks, do you concur
anonymous
  • anonymous
lol
anonymous
  • anonymous
no, I think there is a faster way, by noticing what they can reduce to
anonymous
  • anonymous
I DONT SPEAK MATH.... MUST.... FIND.... TANSLATOR.....
anonymous
  • anonymous
i think this is the only way
anonymous
  • anonymous
reduce the fractions to lowest terms, and then find the product of the denominators?
anonymous
  • anonymous
oh theres redundancy
anonymous
  • anonymous
WHAT IS A LOWEST TERM?
anonymous
  • anonymous
like 3/6 = 1/2 , lowest terms
anonymous
  • anonymous
and what's redundancy... IM IN THE 7TH GRADE
anonymous
  • anonymous
You mean shrink them....
anonymous
  • anonymous
so the answer is 50
anonymous
  • anonymous
12% of those surveyed prefer red = 12/100 = 6/50 = 3/25 14% of those surveyed prefer Orange = 7/50 28% of those surveyed prefer purple = 28/100 = 14/50 30% of those surveyed prefer Blue = 30/100 = 15/50 16% of those surveyed prefer green = 16/100 = 8/50 Notice that MOST of them can be expressed as a whole number out of 25, but not ALL of them...
anonymous
  • anonymous
all the denominators go into that, thats the lowest common multipled of 25,50,25,10,25
anonymous
  • anonymous
so then its 50
anonymous
  • anonymous
While ALL of them can be rewritten as a whole number out of 50, so the answer is....
anonymous
  • anonymous
so how do i figure it out? xD
anonymous
  • anonymous
you rub a magic lamp, and say , genie genie please give me answer
anonymous

if that doesnt work, you can always pay me

MY BRAIN HURTS D:
anonymous
  • anonymous
12% of those surveyed prefer red = 12/100 = 6/50 = 3/25 14% of those surveyed prefer Orange = 7/50 28% of those surveyed prefer purple = 28/100 = 14/50 30% of those surveyed prefer Blue = 30/100 = 15/50 16% of those surveyed prefer green = 16/100 = 8/50 Notice that MOST of them can be expressed as a whole number out of 25, but not ALL of them. While all of them can be rewritten as a fraction with a whole number on top and 50 in the bottom. The top of the fraction is the part and the bottom is the amount that it was "out of".
anonymous
  • anonymous
Good luck, Zelando!
anonymous
  • anonymous
so the smallest number of people is 50?
anonymous
  • anonymous
ok zelando, say you have 12/100 , right ?
anonymous
  • anonymous
YES!
anonymous
  • anonymous
Ok
anonymous
  • anonymous
12/100 * total must equal to an integer
anonymous
  • anonymous
:D
anonymous
  • anonymous
I have smarticles!
anonymous
  • anonymous
12/100 = 3/25, so we need a number that cancel with the denominator
anonymous
  • anonymous
at the very least
anonymous
  • anonymous
TOnks - you earned yourself a medal and you too can :)
anonymous
  • anonymous
so like 12/100 * 25 works, since you get 12/100 = 3/25 and 3/25 * 25 = 3
anonymous
  • anonymous
Wow, thanks
anonymous
  • anonymous
:)
anonymous
  • anonymous
ok so far?
anonymous
  • anonymous
Can - its 50 lmao
anonymous
  • anonymous
i know, im building up to that
anonymous
  • anonymous
lol all drematic
anonymous
  • anonymous
zelando, are you good at analytic geometry , i got a tough problem
anonymous
  • anonymous
find an equation of two tangents through a point outside a circle to a given circle
anonymous
  • anonymous
so youre given P(a,b), do you know calculus ?
anonymous
  • anonymous
tonka, are we good?
anonymous
  • anonymous
What's Analytic geometry?
anonymous
  • anonymous
<---- 7th grader
anonymous
  • anonymous
geometry plus xy plane
anonymous

^-----
anonymous
  • anonymous
I know how to find dimater of a circle...
anonymous
  • anonymous
oh nevermind
anonymous
  • anonymous
lol
