If it takes 4 people 20 days to build a house, how long does it take 6 people. I know the answer is 15 days, but for the life of me I can't figure out the formula for it.

The formula for this problem is: (20 days) / (4 people) x (6 people) = (15 days) This formula means you divide the number of days it takes 4 people to build the house (20 days) by the number of people (4 people), and then multiply that amount by the new number of people, 6. This will give you the number of days it takes 6 people to build the house (15 days).
