Answer:
1/6 of the third workers time
Step-by-step explanation:
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
Let x be the third workers time
Let the completed job time = 1
Time taken for 3 workers to complete the job = 1

now we solve for x
LCD = 2*3 = 6
We multiply the whole equation by 6

3 + 2 +6x = 6
5 + 6x = 6
subtract 5 on both sides
6x = 1
divide both sides by 6
