A factory produces 6 Motorcycles in 9 hours. Write a proportion and solve it to find how many hours it takes to produce 16 motorcycles.

Question

Need help to solve this world problem. 

Answer 1

From the given data,  we form the ratio of hours to # of motorcycles: 9/6.  Reduce it to 3/2.

 

Let h = # of hours to produce 16 motorcycles; we write the same kind of ratio as h/16.

 

We have the proportion 3/2 = h/16.  Solve for h.
