Estimate 10/18

OpenStudy (anonymous):

what do you mean

OpenStudy (jojo4eva):

56%

OpenStudy (jojo4eva):

or 0.56

OpenStudy (jojo4eva):

well ya what do u mean

OpenStudy (anonymous):

like should I round and if so what would it be?

OpenStudy (anonymous):

cause idk im lost

OpenStudy (jojo4eva):

56%

OpenStudy (anonymous):

i think you have to get it to its simplest form

OpenStudy (anonymous):

not precentafes

OpenStudy (jojo4eva):

u should get something like 0.555555555556 when u put it in the calculator

OpenStudy (anonymous):

percentages*

OpenStudy (jojo4eva):

does it want a decimal

OpenStudy (anonymous):

jojo thats not helping xD

OpenStudy (anonymous):

yea you have to get it to its simplest form

OpenStudy (jojo4eva):

what is it its asking for

OpenStudy (anonymous):

okau ty :0

OpenStudy (jojo4eva):

to be simplified so simplest form or to put into a decimal which is it

OpenStudy (anonymous):

no not like that

OpenStudy (jojo4eva):

ok wow that was confusing lol

OpenStudy (anonymous):

jojo what grade are u in o.o

OpenStudy (anonymous):

no decimals you have to put it to its simplest from keeping it as a fraction

OpenStudy (anonymous):

yes ik

OpenStudy (anonymous):

i was trying to explain it to @jojo4eva

OpenStudy (anonymous):

Solve one-sixth plus four-ninths. Then use estimation to check for reasonableness. Show your work. <--- thats the question

OpenStudy (jojo4eva):

oh ok so 5/9 and im a juniro i was trying to figure out what it was when you said estimate

OpenStudy (jojo4eva):

it said estimate and that means several different things especially in math

OpenStudy (anonymous):

the easiest way is to keep it as a fraction

OpenStudy (anonymous):

so the estimation is 5/9....?

OpenStudy (jojo4eva):

well 1/6+4/9 equals 11/18

OpenStudy (anonymous):

what.....

OpenStudy (jojo4eva):

ya 1/6+4/9 is 11/18

OpenStudy (anonymous):

so uh. would it already be simplified or would it be 1/9...?

OpenStudy (jojo4eva):

the common denominator is 18 so you will have 3/18+8/18=11/18

OpenStudy (jojo4eva):

does it give you answer choices

OpenStudy (anonymous):

thats not how I learned how to do it..... fnd the LCD and then subtract the numerator on the left side with the denominator or the right side and then vise versa. then once you got the 2 numbers you add them together....

OpenStudy (anonymous):

and no it doesn't

OpenStudy (jojo4eva):

well in this case the LCD is 18

OpenStudy (anonymous):

yeah I kinda already knew that...

OpenStudy (jojo4eva):

so basically u multiply 1/6 top and bottom by 3 and get 3/18 and you multiply 4/9 top and bottom by 2 and u get 8/18

OpenStudy (jojo4eva):

3/18+8/18 =?

OpenStudy (anonymous):

That doesn't really make sense to me but okay. 3/18+8/18= 11/18

OpenStudy (anonymous):

In the lesson it said to subtract not multiply

OpenStudy (jojo4eva):

im multiplying to make the denominators common but whatever you multiply the top by what u multiplied the bottom. What did u multiply the bottom by to get the LCD for 1/6

OpenStudy (anonymous):

but it's adding not multiplying....

OpenStudy (anonymous):

http://www.youtube.com/watch?v=RIhwfqULbAE

OpenStudy (jojo4eva):

ik but you have to multiply each fraction by a number in order to get the LCD

OpenStudy (anonymous):

are you still confused

OpenStudy (anonymous):

give me back that medal @sunnyshores

OpenStudy (jojo4eva):

ya im telling her that you gotta multiply the fraction by a number in order to find the LCD

OpenStudy (jojo4eva):

but the answer really is 11/18

OpenStudy (anonymous):

cwhatever

OpenStudy (jojo4eva):

U shouldnt be willing to help someone just for medals you should be helping her so that she has the clearest understanding possible @prowrestler
