Answer:
Mr Smith gets a new job, every 5 months on the average.
Step-by-step explanation:
Mr Smith spends an average of 3 months on every job he gets.
Then he spends an average of 2 months in between jobs.
Meaning, on the average, if he has a job, he does it for 3 months, then leaves, lends the next 2 months without a job, then gets another job at the end of the 2 months without a job and then he repeats the cycle of 3 months on the job, 2 months without the job.
So, on the average it takes Mr. Smith, (3+2) months to get a new job.

5 × 5 dancers = 25 dancers
___
Another way to figure this is to write the proportion ...
(seventh-grade dancers)/(all dancers) = 5/16
seventh-grade dancers = (all dancers)×(5/16) = 80×5/16
seventh-grade dancers = 25
