I'm not sure but I think that this is what you have to do:

-3 21/100= -321/100= -100/321

Answer: -100/321

Is this correct? If not, show me how to do it, and give me the correct answer.

Thank you.

**DrBob222**, Monday, November 5, 2007 at 5:12pmThat 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.

**DrBob222**, Monday, November 5, 2007 at 5:17pmYour "indicated" answer is correct. Actually, you didn't finish and come up with a number (an answer) but left it as -100/321. That's ok if that is what your teacher wants.
