It takes 10 workers 10 days to paint 10 houses. How many houses can 5 workers paint in 5 days?
Answer (2)
10 workers paint 10 houses in 10 days .
So . . . 10 workers paint 1 house a day.
So . . . 5 workers paint 1/2 house per day.
So . . . The same 5 workers can paint (5 x 1/2) =*** 2 and 1/2 houses in 5 days***.
Five workers can paint 2.5 houses in 5 days. This rate comes from analyzing how many houses one worker can paint per day. The computation shows that 5 workers over 5 days will yield 2 and 1/2 houses completed.
