Question 234516: please answer. Thanks...Marvin can weed 5 1/2 rows in his garden in 2 hours. At this rate, how many rows can he weed in six hours? Answer by nyc_function(2741) (Show Source):
You can put this solution on YOUR website! Set up the proportion and solve for a letter of choice.
It makes to use r since we are searching for rows.
Let r = how many rows in 6 hours
rows/r = 2 hours/6 hours
I will write 5_1/2 as an improper fraction, which is 11/2.
Then we have (11/2)/r = 2/6
We now simply solve for r.
Can you take it from here?
If not, write back.
