Question
Sheila, Janice, and Karen, working together at the same rate, can complete a job in 3 1/3 days. Working at the same rate, how much of the job could Janice and Karen do in one day?
Solution
First, we need to understand that Sheila, Janice, and Karen together can complete 1 job in 3 1/3 days, which is the same as 10/3 days. This means their combined rate is 1 job per 10/3 days, or (3/10) of a job per day.
Since Janice and Karen work at the same rate as Sheila, Janice and Karen together can also do (3/10) of a job per day.
