Machine A takes 5 hours to make 100 bolts, and machine B takes 3 hours to make 100 bolts. How manybolts will the two machines, working together, make in one hour?

To do this, we need to find how many bolts they make each in 1 hour. 
 

Machine A: 25 bolts per hour        <----- divide by 5

Machine B: 33 1/3 (we can round to 33) bolts per hour        <----- divide by 3

 

Now, we add them together: 25 + 33 = 58

 

Or, if they want the exact amount, it is 25 + 33 1/3 = 58 1/3
