A container has 3 3/8 = 27/8 pounds of flour.
Each student gets 3/16 pound of flour.
If each student in the cooking class needs 3/16 pound of flour and you want to know how many students are in the class, you can calculate this using the following steps:
3 3/8 pounds of flour / 3/16 = 27/8 / 3/16 = 27/8 * 16/3 = 18 students
Result: 18 students are in the cooking class.
