Question

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 of only one person working full time. If one of the people is budgeted for 1/2 of his time to the project and the second person for 1/3 of her time, what part of the third worker's time should be budgeted to this project?

Answer 1

1/2 x 3 = 3/6
second person did 2/6
So the last person only needs to do 1/6 to make it equivalent to one person working full time.
