If it takes 1.5 men 1.5 days to make 1.5 houses how many days will it take 3 workers to make 5 houses?
Techinically, the men aren't directly classified as workers but if your question is indeed quoting that the men are workers then the answer is 7.5 days. To explain, 1.5 times 1.5 =2.25 -> 1.5 houses 3 times 1.5 =4.5 days -> 3 houses 1/1 -> 2/3 houses 3/1->2/3 times 3 = 2 5/2 or 5 divided by 2 =2.5 3 times 2.5 = 7.5 (Please tell me if I am correct for I'm in middle school but can make very careless mistakes.)

Ten people can paint 60 houses in 120 days so five people can paint 30 houses in how many day?
the correct answer is 120 days. You must analyze the relationship of people per house (10 people build 60 houses=6 houses per person over time span). 5 people would then build 30 houses in the exact same time frame.
If 10 people can paint 60 houses 120 days how many days will it take 5 people to paint 30 houses?
This was a previous incorrect answer*DIVIDE BY 2! everything is in half. half the people half the houses then it stands to reason HALF THE DAYS!!!!! the answer is 60*.....Actually the correct answer is 120 days. You must analyze the relationship of people per house (10 people build 60 houses=6 houses per person over time span). To prove this just imagine if the question asked how long 1 person would take to build 6 houses. You would not simply divide by 10 to get 12 days.
