I believe discovering the general rule for finding the number of digits
before the decimal repeats is quite complicated (I'm not positive about
this). But discovering the rule for when the decimal terminates is within
the scope of a middle school student.

How difficult is it to find the rules for decimals that repeat after 1, 2, 3
and 4 digits?
