Please help! Three people who work full time are to work together on a project. but their total time on the project is to be equivalent to that only of one person working full time . if one of the people is budgeted for one half of his time to the project and the second part for one third of her time, what part of the third workers time should be budgeted to this project? A. 1/3 B. 3/5 C. 1/6 D. 1/8

Think about it. One person is budgeted for 1/2 the time and another is budgeted for 1/3 the time. So, the total for those people is 1/2 plus 1/3. Can you add 1/2 plus 1/3?

OpenStudy (anonymous):

yeah its 5/6 correct?

OpenStudy (wolf1728):

Correct. And if the project is budgeted for 1 person, then the time remaining for the third person equals 1 - 5/6 = ???

OpenStudy (anonymous):
