Which of the following fractions would become a repeating decimal?
a.1/8
b.3/4
c.27/36
d.7/9
e.5/8

Because we work in a base 10 number system, any denominator that can be expressed as a multiple of 2s 5s and 10s will not be infinite and therefore not repeating.  1/8 is 1/(2*2*2) which is .125.  3/4 is 3/(2*2) which is .75.  27/36 is a tricky one because it's not in simplest form.  You can divide the top and bottom by 9 to get 3/4 which we already know is .75.  5/8 is 5/(2*2*2) which is .625.  That leaves 7/9.  9 cannot be expressed as a multiple of 2s and 5s ad tens so it must be that one.  7/9 is .777777 repeating.
