For an employee training, the employee to instructor ratio is 24 to 2. if there are 22 instructors for the training, how many employees participated in the training?

So the ratio of employee to instructor is 24:2, which can be reduced to 12:1

If we have 22 instructors, that means there are 12 workers for every intructor (again with the 12:1 raito of employee to instructor). 

Thus, 22 instructors x 12 = # of employees = 264 employees
