What is the reciprocal of -3.21?
I'm not sure but I think that this is what you have to do:
-3 21/100= -321/100= -100/321
Is this correct? If not, show me how to do it, and give me the correct answer.

That is one way to do it.
The reciprocal of a number is the number divided INTO 1.
Take the reciprocal of -3.21
1/-3.21 = -0.3115 which I would round to -0.312.
You actually did yours this way.
-3.21 x (100/100) = -321/100
Reciprocal is 100/-321 and I plug that into my calculator and get -0.3115 which I would round to -0.312.
