To determine which decimal is equivalent to 511, we first need to clarify that the number 511 is actually an integer and could be represented as a decimal if we place it over 1. So, 511 can be expressed as \( 511.0 \) or simply \( 511 \).
Now let's analyze the options provided:
1. **0.45** – This is simply 45 hundredths.
2. **0.4545** – This is 45 hundredths plus an additional 5 thousandths, or \( \frac{4545}{10000} \).
3. **0.45̅** (where the bar indicates that the digits 45 repeat infinitely) – This represents the repeating decimal \( 0.454545...\), which can be converted to a fraction as \( \frac{45}{99} = \frac{5}{11} \).
4. **0.44444444...** – This represents the repeating decimal \( 0.4444...\), which can be converted to a fraction as \( \frac{4}{9} \).
None of the decimal options listed are equivalent to 511. Therefore, the correct answer from the options given is that none of them equal 511.
