How much chocolate person get if 1/2 pound of chocolate should equal about five people

Everyone gets a tenth of a pound of chocolate.

Well you do 5 / 1/2. and then you change the 5 to 5/1  and then we flip the reciprocal to 2/1 

so it should look like this    5             2
                                          ---      x    --      which would be 10/1 and then you 
                                           1             1

divde 10/1 which would be 10 pounds of chocolate for 5 people hope that helped
