Answer: Only the fraction 11/99 represents a decimal where three digits repeat.
Explanation:
To convert a fraction to a decimal, we divide the numerator by the denominator. In this case, 11 divided by 99 is 0.11111111..., which is a repeating decimal with three digits.
The other fractions do not represent decimals with three repeating digits. For example, 103 divided by 665 is 0.1550625, which is a non-repeating decimal.
