Given: Dave bought 11 / 20 pounds of chocolate

             Sam purchased 7 / 10 pounds of chocolate.

In order to determine how many more pounds of chocolate Sam purchased than Dave, simply change both fractions into decimal form, then subtract the amount of chocolate that was bought by Sam to the amount of chocolate bought by Dave.

11 / 20 lb = 0.55 lb

7/10 = 0.7 lb

0.7 lb - 0.55 lb = 0.15 lb

Sam purchased 0.15 more pounds of chocolate than Dave.
