If it takes 7 people to dig a ditch in 8 days how many people would it take to dig a ditch in a half of a day?

To find out how many people it would take to dig the ditch in half a day, we first calculate the total amount of work in "person-days." If 7 people can complete the work in 8 days, that amounts to 7 people × 8 days = 56 person-days. To complete the work in half a day, you would need 56 person-days ÷ 0.5 days = 112 people. Therefore, it would take 112 people to dig the ditch in half a day.
