if it takes 4 men 6 hours to repair rust how long will it take seven men to do the job if they work at the same rate

3.43 I believe

Step-by-step explanation:

I'm not too sure but I tried this:

4 men take 6 hours mean it is a ratio of 4:6 so 1 : 1.5 I then multiplied 1.5 by 7 and got 10.5 I found what percent 6 is of 10.5 and got about 57 percent I used that percent and multiplied it by 6 and got 3.42857 ...

Or what percent 4 is of 7. I got the same answer with less steps.

3 1/3 hours is the answer
