John earns $12 in 2/3 of an hour what is the unit rate

To answer this question we have to divide 2/3 by 12. 
To divide fractions multiply by the reciprocal of the second fraction.

2        1           2                          1 
_   x  __   =    __   (simplify) =    __

3       12         36                        18

The correct answer is 1/8
