Final answer:
Option B) --l/-m is equivalent to -l/-m as the double negative on 'l' cancels out, making it the same as l/m.
Step-by-step explanation:
The question asks which expressions are equivalent to -l/-m. When simplifying these types of expressions, we apply the rule that a negative divided by a negative results in a positive. Therefore, -l/-m simplifies to l/m.
Looking at the options provided:
- A) -l/m is not equivalent because it represents a negative divided by a positive, resulting in a negative.
- B) --l/-m is equivalent because the double negative on 'l' cancels out, making it l/-m, which is then equivalent to -l/m due to a single negative sign.
- C) signifies that none of the provided answers are correct.
