Step-by-step explanation:
In one day, one worker weeds [tex]\huge\bold{1/5 x 1/12 = 1/60}[/tex]1/5 x 1/12 = 1/60 of the field.
In one day, six workers could weed 6/60 or 1/10 of the field, so it would take them 10 days to weed the whole field.
In one day, 15 workers could weed 15/60 or 1/4 of the field, so the whole field would take 4 days.
If 5 workers take 12 days
Then , 1 worker will take = 5 × 12 = 60 days
So, 15 workers will take = 60 ÷ 15 = 4 days
