How many digits long could the repeating cycle of a repeating decimal be if the denominator of the rational number is 7? (1 point)

O any finite length

O up to six digits long

O infinitely long

O up to seven digits long

The repeating cycle of a repeating decimal for a rational number with a denominator of 7 could be up to six digits long. Therefore, the correct answer is O up to six digits long.

The repeating cycle of a repeating decimal with a denominator of 7 can be up to six digits long. Hence, the answer is:

O up to six digits long
