How many digits long could the repeating cycle of a repeating decimal be if the denominator of the rational number is 7?(1 point)Responsesup to seven digits longup to seven digits longup to six digits longup to six digits longinfinitely longinfinitely longany finite length

Answer 1

The repeating cycle of a repeating decimal is determined by the denominator of the rational number when expressed in lowest terms. For a denominator of 7, which is a prime number, the repeating cycle can have a maximum length equal to the denominator (in this case, 7).

Therefore, the correct response is up to seven digits long.

Answer 3

I apologize for any confusion. Let’s clarify:

When you have a rational number with a denominator of 7, the repeating decimal can indeed have a repeating cycle up to a maximum length of 6 digits. This is due to the property of repeating decimals and their relationship with the denominators.

• The maximum length of the repeating cycle is determined by the factors of 10 relative to the denominator. For 7, the cycle length is \( \phi(7) = 6 \), where \( \phi \) is Euler's totient function.

Thus, the correct answer is up to six digits long. Please let me know if you have any further questions!
