To determine which choice is NOT equal to the others, we need to evaluate each expression. The double square brackets \( [[ \cdot ]] \) typically denote the floor function, which rounds down to the nearest integer.
1. **A. -[[2/5]]**
- \( 2/5 = 0.4 \)
- The floor of \( 0.4 \) is \( 0 \).
- Therefore, \( -[[2/5]] = -0 = 0 \).
2. **B. [[-2/5]]**
- \( -2/5 = -0.4 \)
- The floor of \( -0.4 \) is \( -1 \).
- So, \( [[-2/5]] = -1 \).
3. **C. [[2/5]]**
- As previously calculated, \( [[2/5]] = 0 \).
4. **D. [[2/-5]]**
- \( 2/-5 = -0.4 \)
- The floor of \( -0.4 \) is also \( -1 \).
- Therefore, \( [[2/-5]] = -1 \).
Now we can summarize the results:
- A. \( -[[2/5]] = 0 \)
- B. \( [[-2/5]] = -1 \)
- C. \( [[2/5]] = 0 \)
- D. \( [[2/-5]] = -1 \)
From this evaluation, we see that:
- A and C equal \( 0 \).
- B and D equal \( -1 \).
Thus, the choice that is NOT equal to the others is:
**B. [[-2/5]]**
1. **A. -[[2/5]]**
- \( 2/5 = 0.4 \)
- The floor of \( 0.4 \) is \( 0 \).
- Therefore, \( -[[2/5]] = -0 = 0 \).
2. **B. [[-2/5]]**
- \( -2/5 = -0.4 \)
- The floor of \( -0.4 \) is \( -1 \).
- So, \( [[-2/5]] = -1 \).
3. **C. [[2/5]]**
- As previously calculated, \( [[2/5]] = 0 \).
4. **D. [[2/-5]]**
- \( 2/-5 = -0.4 \)
- The floor of \( -0.4 \) is also \( -1 \).
- Therefore, \( [[2/-5]] = -1 \).
Now we can summarize the results:
- A. \( -[[2/5]] = 0 \)
- B. \( [[-2/5]] = -1 \)
- C. \( [[2/5]] = 0 \)
- D. \( [[2/-5]] = -1 \)
From this evaluation, we see that:
- A and C equal \( 0 \).
- B and D equal \( -1 \).
Thus, the choice that is NOT equal to the others is:
**B. [[-2/5]]**

To find another way to write \(-\frac{7}{8}\), we need to evaluate each answer choice:
1. **A. [[7/8]]**
- \( \frac{7}{8} = 0.875 \)
- The floor function \( [[7/8]] \) (which denotes the greatest integer less than or equal to \( 0.875 \)) results in \( 0 \).
- So, \( [[7/8]] = 0 \).
2. **B. -[[7/8]]**
- As determined above, \( [[7/8]] = 0 \).
- Therefore, \( -[[7/8]] = -0 = 0 \).
3. **C. -[[7/-8]]**
- \( \frac{7}{-8} = -0.875 \)
- The floor function \( [[7/-8]] \) results in \( -1 \) (since it rounds down).
- Thus, \( -[[7/-8]] = -(-1) = 1 \).
Now, let's summarize the results:
- A. \( [[7/8]] = 0 \)
- B. \( -[[7/8]] = 0 \)
- C. \( -[[7/-8]] = 1 \)
None of the choices directly yield \(-\frac{7}{8}\) (which is \(-0.875\)). However, the results clearly show:
- A and B both result in \(0\).
- C results in \(1\).
Since we are looking for an expression that equals \(-\frac{7}{8}\), and none of the provided options yield this, the correct approach would be:
None of the given choices correctly represent \(-\frac{7}{8}\).
However, if the question is specifically looking for which expression is negative or closest (with either \(-1\) or a negative value), the most equivalent understanding in terms of representation could be option B and its negative aspects, even though it evaluates to \(0\).
If you need a more specific answer regarding the intent behind sourcing negative values, please clarify.
1. **A. [[7/8]]**
- \( \frac{7}{8} = 0.875 \)
- The floor function \( [[7/8]] \) (which denotes the greatest integer less than or equal to \( 0.875 \)) results in \( 0 \).
- So, \( [[7/8]] = 0 \).
2. **B. -[[7/8]]**
- As determined above, \( [[7/8]] = 0 \).
- Therefore, \( -[[7/8]] = -0 = 0 \).
3. **C. -[[7/-8]]**
- \( \frac{7}{-8} = -0.875 \)
- The floor function \( [[7/-8]] \) results in \( -1 \) (since it rounds down).
- Thus, \( -[[7/-8]] = -(-1) = 1 \).

Thank you for your follow-up! It seems there may be confusion about the context or specific question you're referencing. Let's clarify based on your new message, as it appears you might have intended to communicate a specific set of responses.
From what you've shared:
1. **You mentioned that \(-\frac{7}{8}\) could be represented by "B. -[[7/8]]".**
2. **You also stated that the answer is "[[2/5]]", which was not part of the original question.**
3. **And you provided "9" as a third answer.**
If we are focusing again on \(-\frac{7}{8}\), we previously discussed how this value doesn’t directly correspond to the floor values provided in the choices.
To calculate mathematically:
- **For \(-\frac{7}{8}\):**
- This equals \(-0.875\).
- None of the expressions provided (A, B, C from the original question) equate directly to \(-0.875\), although option B gets close in approach by utilizing the floor function with negative values, resulting in 0 but marked in an inequality context.
### Summary based on your latest message:
- If the goal is to reiterate or clarify your provided mappings:
- **"Answer is `[[2/5]]`"** can be interpreted contextually, although we were discussing \(-\frac{7}{8}\) previously.
- **"2nd answer is `-[[7/8]]`"** correctly references the negative impact to yield a different perspective.
- **"3rd answer is `9`"** might introduce a new variable unrelated within the earlier context.
Please correct me if there's a specific question or context you wish to focus on! If you need to find equivalents, feel free to ask, and I’ll help clarify any mathematics or logic behind your queries.
