Final answer:
The fraction 18/18 equals 1 when calculated. None of the provided decimal options (0.125, 0.125 with an overline, 0.125 without an overline) are equal to 1. There appears to be an error in the question or answer choices.
Step-by-step explanation:
The question is asking which decimal number is equivalent to the fraction 18/18. Let's solve this step by step:
- First, we recognize that 18/18 is a division of the same number by itself, which always equals 1.
- Therefore, none of the decimal options provided (0.125, 0.125 with an overline, 0.125 without an overline) are equal to 1.
- In fact, each of the provided options is less than 1, so it's clear that none of them represent the value of 18/18.
In conclusion, if 18/18 was an option in decimal form, it would simply be 1.0, but since it's not listed, there seems to be a mistake in the question or answer choices.
