Do you mean 2/(x/y)? Or (2/x)/y? Or something else?

What are the instructions? Were you given values for the variables, and you're supposed to evaluate? Are you supposed to simplify? Or something else?

When you reply, please show all of the steps you have tried so far. Thank you.

Unfortunately, this is ambiguous. A fraction is "(this) divided by (that)", not "(this) divided by (that) divided by (the other)". You can divide by a fraction -- 2 / (x/y) -- or divide a fraction by something -- (2/x) / y< but "2/x/y" has no fixed meaning.

If you mean (2/x) / y, then your answer is correct. Otherwise, not. But I'm afraid it isn't possible to give an absolute, given the information available to this point. Sorry. :oops:
