    the rate for each is 1job/6hrs,or 1job/7hours

    timetogehter=1job/combined rate
    = 1/(1/6 + 1/7)

    go for it.

    OK so find LCD which is 24, than multiply 4*1 and 3*1 making first fraction 4/24 and the second 3/24 which is 7/24. Than flip and 24/7 making the answer somewhere around 3/7 hours and I'm not sure on how to convert that into more technical answer... So what do you think?
