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):

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):
@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

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):
