    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.
