  1. assuming you mean
    = (x(2x-1)(2x+1))/(3(2x+1)(2x-1))
    = x/3
    = 3333

    7 men for 7 hrs for 1 day = 1 work unit
    7 men for 1 hr for 1 day = 1/7 wu
    1 man for 1 hour for 1 day = 1/49 wu

    5men * 5hrs * 5days = 125/49 wu

    or, just do the ratios in-line
    (5/7)(5/7)(5/7)=(5/7)^3*(7) = 125/49
