All "whole" numbers have a denominator of 1 not 0.

Thank you!

I switched it and got -0/1, but that didn't make sense. I forgot the rule that -1 is always -1.

(6/3)=2...
2(-1/2)=-1...
the reciprocal of -1 is always -1

I understand that to find the reciprocal of something you switch the numerator with the denominator, but how would you solve a more complex problem like this?

Find the reciprocal of:   (-1/2)(6/3)

Thanks!
Sari
