Question

For an employee training, the employee to instructor ratio is 18 to 2. If there are 20 instructors for the training, how many employees participated in the training?

Answer 1

The ratio 18 to 2 can be divided by two to get a 9 to 1 ratio, so every every 1 instructor they can have 9 employees.

Multiply 9 by the number of instructors to get total:

20 * 9 = 180 employees.
