OpenStudy (rebeccapink6398):

OpenStudy (anonymous):

I got C as well.

OpenStudy (afrodiddle):

This is simple.

OpenStudy (baby_bear69):

Well, 31\8 = 3.875 which is less than 3.89

OpenStudy (afrodiddle):

We automatically know 3.87 is bigger than 3.7

OpenStudy (afrodiddle):

so we list 3.7 , 3.87

OpenStudy (afrodiddle):

So be is crossed out

OpenStudy (afrodiddle):

"B"

OpenStudy (afrodiddle):

Next, tell me what is 31 divided by 8?

OpenStudy (anonymous):

it mite be c

OpenStudy (anonymous):

Least to greatest: 3.7, 3 3/4 (also known as 3.75), followed by 31/8 (3.875), and finally 3.89.

OpenStudy (rebeccapink6398):

what i got is 3.7 then 3.75 then 3.89 then 3.875

OpenStudy (afrodiddle):

Yup.

OpenStudy (afrodiddle):

You're good to go! :)

OpenStudy (anonymous):

But 3.875 is smaller than 3.89...

OpenStudy (afrodiddle):

ahh yes.

OpenStudy (anonymous):

C is the answer.

OpenStudy (rebeccapink6398):

thank you :D

OpenStudy (afrodiddle):

I did not even notice she put that, good eye @stellie1009

OpenStudy (anonymous):

haha no problem:D

OpenStudy (rebeccapink6398):

@stellie1009 thats what i also thought./.... but i was not sure so i asked for people to check my work

OpenStudy (amistre64):

we could have multiplied everything by 8 and compared the results as well.

OpenStudy (amistre64):

31/8 , 3.7, 3+3/4, 3.89 31(8)/8 , 3.7(8), 3(8)+3(8)/4, 3.89(8) 31, 3.7(8), 24+3(2), 3.89(8) 31, 29.6 , 30, 31.12

OpenStudy (afrodiddle):

when you are trying to convert fractions to digits dont forget that you can divide the numerator(top) by the denominator (bottom)

OpenStudy (afrodiddle):

to get the digit form.

OpenStudy (rebeccapink6398):

ummm.. yeah thats what i did for alll the fractions. i thought thats how your supposed to do all of them to make them into decimals?

OpenStudy (afrodiddle):

yes, just making sure you knew. :)

OpenStudy (rebeccapink6398):

... soo am i right or wrong?

OpenStudy (afrodiddle):

you are right.

OpenStudy (afrodiddle):

It is definitely "C"

OpenStudy (rebeccapink6398):

:D yay thxx but what about that 3.875.. is that in the right place!?

OpenStudy (afrodiddle):

3.89 is last

OpenStudy (afrodiddle):

31/8 is second to last

OpenStudy (afrodiddle):

the order is : 3.7 , 3 3/4 , 31/8 , 3.89

OpenStudy (rebeccapink6398):

OpenStudy (afrodiddle):
