put this solution on YOUR website! If it takes 3 workers 15 days to complete a job, how long
would it take 5 workers to complete the same job?
The least common multiple of 3 and 5 workers is 15 workers.
it takes 3 workers 15 days to complete a job
Therefore it would take 15 workers (5 times as many workers)
only 1/5th of 15 days or 3 days to complete a job.
Therefore it would take 5 workers (only 1/3 as many workers)
3 times 3 days or 9 days to complete a job.
