The answer is 1 however i am getting 0.75. Could anyone tell me where i am going wrongIn one half the time Abby can produce three times as much work as Beth. Beth can do in twice the time 1/3 as much work as carol. If carol does a job in one hour , how many hours will it take Abby to do the same job. ?
1/3 of work in 2 hours
so for one job it takes 6 hours.
6 * (2/3) = 4 hours.
So in 4 hours Abby does 3 jobs
so 1 job takes 3/4 hours.
