5 workers making 6 garments each = 30 garments per day
3 workers making 4 garments each = 12 garments per day
1 / 9 workers making 12 garments = 12/54 garments per day Add the number of workers and the number of garments per day.
9 workers make 54 garments per day
To find the average number of garments per worker per day, divide the number of garments per day by the number of workers.
54 / 9 = 6 garments per worker per day
