6tractors take 8 days to collect the harvest. how long would it take 9 tractors to do the same amount of work?

5 days

Step-by-step explanation:

6 tractors = 8 days

double the tractors = half the time  

(2 x 6 tractors = x 8 days)

1.5 the tractors, means of the time

1.5 x 6 tractors = x 8 days

    9 tractors =    

                     = 5.33 days

NOTE: I really think the answer is 6 days but I could not figure out a mathematical way to get that answer.

idk bring the function back   im not smart
