i am figuring it out to help ok
OpenStudy (anonymous):
thanks
OpenStudy (welshfella):
0.24.. * 100 = 24.24.....
0.24.. * 1 = 0.24......
Subtract 99 = 24
so its 24/99
OpenStudy (jennyrlz):
what?
OpenStudy (jennyrlz):
it would 24/100
you moved the decimal two places :)

thats not a opian
OpenStudy (jennyrlz):
but you need to simplif that
OpenStudy (welshfella):
the fraction is 0.2424242424... recurring
OpenStudy (jennyrlz):
still you can round it
OpenStudy (welshfella):
try dividing 24 by 99 on your calculator and see what you get

so first you take 3.24 move the decimal point over and 324 over a thousand.
OpenStudy (jennyrlz):
let me show you how i would do it then you can compare it to the choices or other answers :P
OpenStudy (anonymous):
so what is it
OpenStudy (jennyrlz):
24/100
divide both sides by 4
6/25
OpenStudy (welshfella):
oh yes sorry i forgot the 3 the answer is 3 24/99

OpenStudy (jennyrlz):
meaning we end up with 3 6/25
OpenStudy (anonymous):
the only one like that is 3 6/97
OpenStudy (jennyrlz):
actually now that i think about i would go with @welshfella
OpenStudy (anonymous):
\[324/1000 \]then divide top by 4 then bottom by 4
OpenStudy (welshfella):
you said 0.24 repeating which i took to mean 0.242424 etc

when you put 24/99 in the calculator you get .24242424
OpenStudy (jennyrlz):
meaning he is right
OpenStudy (anonymous):
so 324 divided by 4 is 81
OpenStudy (jennyrlz):
actauly i think that can be simplified
OpenStudy (welshfella):
if its not repaeating then it is 3 6/25 as yoiu said

3.24
OpenStudy (jennyrlz):
8/33
OpenStudy (jennyrlz):
3 8/33
OpenStudy (jennyrlz):
24/99 can be simplified by dividing both sides by 3
OpenStudy (anonymous):

take1000 divide by 4 = 250
OpenStudy (jennyrlz):
giving us 8/33
OpenStudy (welshfella):
do you see what i mean by 'repeating'.
like 0.33333.. = 1/3
OpenStudy (jennyrlz):
i would actually give the medal to welshfella he was the one that was on the right track to begin with
OpenStudy (anonymous):
that is 81 over 250
