I am trying to study for a basic math entrance exam and can not recall how to work out the following question. Here it is:

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 a second person for 1/3 of her time,what part of the third worker's time should be budgeted to this project?
Answers to pick from are:
1. 1/3
2. 3/5
3. 1/6
4. 1/8
Not sure of even remember where to begin to work this problem out.

Answer 1

1/2 + 1/3 = 3/6 + 2/6 = 5/6

1 - 5/6 = 1/6

Answer 2

Heather, I cannot believe you typed the same Math Problem I did. This is surely fate. I am studying for a College Placement Test for Del Tech. I'll be checking for an answer so that we can finally get the answer. Good luck to you and God Bless
