Answer:
1) 4 1/2 days. 2) 4
Step-by-step explanation:
If Two people can do a job in 3 days. they each represent 1.5 of a day, this is due to 3/2 being 1.5; Now if you take one away then you would need to add another 1.5 days being 4.5 or 4 1/2. If each person represents 1.5 days then for every person you subtract 1.5 days thus 3people;1.5days | 4people:0days
technically speaking we can’t do 3 1/6 persons because we can’t have pieces of humans do tasks. thus 4 people would be the minimum requirement for 1 day work.
