Answer:
3 teaspoons. 
Step-by-step explanation:
I am going to do this by figuring out how many teaspoons of molasses is need to serve 2 and then multiply that number by 3. because 3 x 2 = 6.
10 divided by 5 is 2.  5 divided by 5 equals 1. This means that to feed 2 people you need 1 teaspoon of molasses. 
1 tsp + 1 tsp + 1 tsp = 3 tsp. 
This means that I need 3 tsp of molasses to feed 6 people.
