How do I set this problem up?

Question

A large container of prune juice used 14/16 of a pound of prunes. If a small container used 2/3 of the amount of a large container, how many pounds of prunes would a small container use?

Answer 1

Let x = number of pounds of prunes a small container would use

x = (2/3)(14/16)

x = 7/12
