very carefully

- anonymous

can you manipulate the division so you are dividing by a whole number and not change the value of that fraction?

- anonymous

what i dont get what yew are saying

- anonymous

so...what you are doing is trying to divide correct?

- anonymous

yes

- anonymous

so..to make things easier...you want to divide by a whole number...dividing by a decimal like 166.97 is tough
So my question to you was...can you change that division, so that you have a whole number you divide by and not change the value of the problem

- anonymous

soo like 1178/166,970

- anonymous

okay nice!...you are getting the idea...but your numbers a bit off.

- anonymous

so you changed the divisor by a multiple of 1000...what i mean is you multiplied the divisor (166.97) by 1000 to get 166970
but if you do that...you must also multipy the divident (1178) by 1000 or you change the value

- anonymous

ok im in 6th grade and yew are talking on a 10th grade level can yew break it down please :)

- anonymous

okay...one second

- anonymous

ok

- anonymous

this is what you are doing right?

- anonymous

ya i think

- anonymous

what i am suggesting is that you do something...so that the bottom of this fraction is a whole number...like this

##### 1 Attachment

- anonymous

that's what you thought of when you gave me your last answer

- anonymous

ok thats wat im doing

- anonymous

okay good...BUT...you cannot just do that...because if you multipy by 1/1000 like that...then you are changing the value of your fraction

- anonymous

so what do you think we can do...so that you don't change the value of your fraction...do something about that 1/1000

- anonymous

try viewing my question

- anonymous

huh?

- anonymous

so mastery...do you have some clever way...to change that 1/1000 so that it won't mess with the value of your fraction?

- anonymous

call me taylor i didt mean to put mastery and wat

- anonymous

k, taylor...did they tell you in class that when you multiply anything by 1 then it does not change the value?

- anonymous

nope

- anonymous

so for example...: 5*1 = 5; 13*1 = 13; 1512*1 = 1512

- anonymous

so anytime you multiply something by 1 ...you never change the value...that includes fractions

- anonymous

i dont know anything about that

- anonymous

ooooooo i think i get it

- anonymous

so for example: 1/2 * 1 = 1/2
3/5 *1 =3/5
37383 / 37382 *1 = 37383/37382
and so on

- anonymous

just any fraction times 1 is still the same fraction...

- anonymous

okay the next thing you need to know is that if you have a fraction...that has the same number on top as on the bottom...then it's always equal to 1

- anonymous

do you believe that?

- anonymous

like... 3/3 = 1
or 5/5 =1
78/78 =1
1000/1000 = 1

- anonymous

im really confused

- anonymous

well, let's do one step at a time...do you believe my last statement...as long as the top number is equal to the bottom number it is equal to 1

- anonymous

like this:

##### 1 Attachment

- anonymous

ok

- anonymous

so what im trying to say is that what you did earlier:

##### 1 Attachment

- anonymous

is almost correct...but you cannot multiply by just 1/1000 you have to do it by 1000/1000...like this:

##### 1 Attachment

- anonymous

because this way...you multiplied by something that is equal to 1 and that won't change the value of your fraction, but now you have a whole number on the bottom...and you can simplify or divide

- anonymous

is there an easier way to do this

- anonymous

not really
the only thing you can do to make the numbers look a bit smaller is to use 100/100 instead of 1000/1000...cause 100/100 will do the trick...you went a bit overboard with multiplying by 1000/1000...but it gets the job done:
so you can do this:

##### 1 Attachment

- anonymous

see how doing it this way also gives you a whole number on the bottom...now you can simplify or divide as well

- anonymous

i dont get what yew are saying!!

- anonymous

which part?

- anonymous

the hole thing'

- anonymous

sorry you are gonna have to be more specific

- anonymous

eveything u said so far

- anonymous

please go back to the beginning of this thread and re-read what i wrote...hopefully you will have a more specific question once you do that

- anonymous

ok

- anonymous

still confused

- anonymous

which part?

- anonymous

what was the last line that made sense to you?

- anonymous

never mind i got it!!!!!!!!! thanx sooo much

- anonymous

cool, you are welcome! I'm glad you didn't give up. Good luck

- anonymous

thanx!
